| 1 | Shaking table experimental study of recycled concrete frame-shear wall structures显示文摘In this study, four 1/5 scaled shaking table tests were conducted to investigate the seismic performance of recycled concrete frame-shear wall structures with different recycled aggregates replacement rates and concealed bracing detail. The four tested structures included one normal concrete model, one recycled coarse aggregate concrete model, and two recycled coarse and fi ne aggregate concrete models with or without concealed bracings inside the shear walls. The dynamic characteristics, dynamic response and failure mode of each model were compared and analyzed. Finite element models were also developed and nonlinear time-history response analysis was conducted. The test and analysis results show that the seismic performance of the recycled coarse aggregate concrete frame-shear wall structure is slightly worse than the normal concrete structure. The seismic resistance capacity of the recycled concrete frame-shear wall structure can be greatly improved by setting up concealed bracings inside the walls. With appropriate design, the recycled coarse aggregate concrete frame-shear wall structure and recycled concrete structure with concealed bracings inside the walls can be applied in buildings. | Zhang Jianwei Cao Wanlin Meng Shaobin Yu Cheng Dong Hongying | 2014 | Earthquake Engineering and Engineering Vibration2014，13，2： | 8 |
| 2 | Experimental and analytical study on seismic behavior of steel-concrete multienergy dissipation composite shear walls显示文摘In this paper, a steel-concrete multi-energy dissipation composite shear wall, comprised of steel-reinforced concrete(SRC) columns, steel plate(SP) deep beams, a concrete wall and energy dissipation strips, is proposed. In order to study the multi-energy dissipation behavior and restorability after an earthquake, two stages of low cyclic loading tests were carried out on ten test specimens. In the first stage, test on five specimens with different number of SP deep beams was carried out, and the test lasted until the displacement drift reached 2%. In the second stage, thin SPs were welded to both sides of the five specimens tested in the first stage, and the same test was carried out on the repaired specimens(designated as new specimens). The load-bearing capacity, stiffness, ductility, hysteretic behavior and failure characteristics were analyzed for both stages and the results are discussed herein. Extrapolating from these results, strength calculation models and formulas are proposed herein and simulations using ABAQUS carried out; they show good agreement with the test results. The study demonstrates that SRC columns, SP deep beams, concrete wall and energy dissipation strips cooperate well and play an important role in energy dissipation. In addition, this study shows that the shear wall has good recoverability after an earthquake, and that the welding of thin SP's to repair a deformed wall is a practicable technique. | Dong Hongying Cao Wanlin Wu Haipeng Qiao Qiyun Yu Chuanpeng | 2015 | Earthquake Engineering and Engineering Vibration2015，14，1： | 4 |
| 3 | Research on seismic performance of shear walls with concrete filled steel tube columns and concealed steel trusses显示文摘In order to further improve the seismic performance of RC shear walls, a new composite shear wall with concrete filled steel tube (CFT) columns and concealed steel trusses is proposed. This new shear wall is a double composite shear wall; the first composite being the use of three different force systems, CFT, steel truss and shear wall, and the second the use of two different materials, steel and concrete. Three 1/5 scaled experimental specimens: a traditional RC shear wall, a shear wall with CFT columns, and a shear wall with CFT columns and concealed steel trusses, were tested under cyclic loading and the seismic performance indices of the shear walls were comparatively analyzed. Based on the data from these experiments, a thorough elastic-plastic finite element analysis and parametric analysis of the new shear walls were carried out using ABAQUS software. The finite element results of deformation, stress distribution, and the evolution of cracks in each phase were compared with the experimental results and showed good agreement. A mechanical model was also established for calculating the load-carrying capacity of the new composite shear walls. The results show that this new type of shear wall has improved seismic performance over the other two types of shear walls tested. | Cao Wanlin Zhang Jianwei Dong Hongying Wang Min | 2011 | Earthquake Engineering and Engineering Vibration2011，10，4： | 3 |

| 5 | Analysis and seismic tests of composite shear walls with CFST columns and steel plate deep beams显示文摘A composite shear wall concept based on concrete filled steel tube(CFST)columns and steel plate(SP)deep beams is proposed and examined in this study.The new wall is composed of three different energy dissipation elements:CFST columns;SP deep beams;and reinforced concrete(RC)strips.The RC strips are intended to allow the core structural elements-the CFST columns and SP deep beams-to work as a single structure to consume energy.Six specimens of different configurations were tested under cyclic loading.The resulting data are analyzed herein.In addition,numerical simulations of the stress and damage processes for each specimen were carried out,and simulations were completed for a range of location and span-height ratio variations for the SP beams.The simulations show good agreement with the test results.The core structure exhibits a ductile yielding mechanism characteristic of strong column-weak beam structures,hysteretic curves are plump and the composite shear wall exhibits several seismic defense lines.The deformation of the shear wall specimens with encased CFST column and SP deep beam design appears to be closer to that of entire shear walls.Establishing optimal design parameters for the configuration of SP deep beams is pivotal to the best seismic behavior of the wall.The new composite shear wall is therefore suitable for use in the seismic design of building structures. | Dong Hongying Cao Wanlin Wu Haipeng Zhang Jianwei Xu Fangfang | 2013 | Earthquake Engineering and Engineering Vibration2013，12，4： | 1 |

| 7 | Experimental study on seismic behavior of mid-rise RC shear wall with concealed truss显示文摘In this paper,mid-rise shear wall with concealed truss was proposed.This new composite shear wall includes two kinds of composition:one is the composition of two bearing systems,including truss and shear wall,and the other is the composition of two materials,including steel and concrete.Therefore,it is a double composite shear wall.The experimental study on the seismic behavior of six 1/3 scale mid-rise shear walls,including an ordinary mid-rise shear wall,a mid-rise shear wall with steel frame,and four mid-rise shear wall with concealed truss made of different materials,was studied.Based on the experimental study,the stiffness and its attenuation,bearing capacity,ductility,hysteretic property,energy dissipation,and failure phenomena of each shear wall were contrastively analyzed.The formulas of bearing capacity and stiffness were established.The results obtained from the formulas and those from experiment are in good agreement.Some suggestions for seismic design of shear wall are given in this paper.The experimental results show that the seismic behavior of the mid-rise shear wall with steel frame and that of every truss with different materials is obviously improved. | Wanlin CAO Jianwei ZHANG Jingna ZHANG Min WANG | 2009 | Frontiers of Structural and Civil Engineering2009，3，4： | 1 |

| 9 | Initiation of dendritic NMDA spikes co-regulated via distance-dependent and dynamic distribution of the spine number and morphology in neuron dendrites显示文摘Dendritic spines are small membranous protrusions that receive synaptic inputs from other neurons,enabling the initiation of dendritic N-methyl-D-aspartic(NMDA)spikes and somatic action potentials.During learning and memory processes,both the number of spines on a dendrite and the morphology of individual spines are constantly changing.The individual influence of spine number and morphology on dendritic NMDA spikes has already been revealed,but the functional significance of the coregulation of spine number and morphology on NMDA spikes remains elusive.Here,we systematically investigated the initiation of local dendritic NMDA spikes by the dynamic distributions of the spine number and morphology on single dendrites in reconstructed neuron models.Different from the traditional cognition,we found the threshold number of spines required to generate local dendrite NMDA spikes on distal dendrites is fewer than that on proximal ones,because the thinner distal dendrites own higher impedance.As for the spine morphology,the presence of moreα-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid(AMPA)receptors on the spine leads to larger NMDA spikes rather than an increase in the spine dimension alone.Furthermore,we first suggested that a single dendrite containing spines with gradually increasing head diameters away from the soma could generate larger NMDA spikes than that irrational distribution of spine morphology containing spines with decreasing head diameters,which can be compensated by the increasing spine number.Complementarily,the distance-dependent distribution of spine number and morphology co-regulate the intension of dendritic NMDA spikes.These findings about the threshold for NMDA spikes provide novel insights into the role of the irrational dynamic distribution of the spine number and morphology in senescence and disease processes such as Alzheimer’s disease,schizophrenia,and Parkinson’s disease,which causes abnormal neuron firing. | CAO YuWei SHEN Chun QIU Hu GUO WanLin | 2023 | Science China(Technological Sciences)2023，66，2： | 0 |
| 10 | Graphene binding on black phosphorus enables high on/off ratios and mobility显示文摘Graphene is one of the most promising candidates for integrated circuits due to its robustness against short-channel effects,inherent high carrier mobility and desired gapless nature for Ohmic contact,but it is difficult to achieve satisfactory on/off ratios even at the expense of its carrier mobility,limiting its device applications.Here,we present a strategy to realize high back-gate switching ratios in a graphene monolayer with well-maintained high mobility by forming a vertical heterostructure with a black phosphorus multi-layer.By local current annealing,strain is introduced within an established area of the graphene,which forms a reflective interface with the rest of the strain-free area and thus generates a robust off-state via local current depletion.Applying a positive back-gate voltage to the heterostructure can keep the black phosphorus insulating,while a negative back-gate voltage changes the black phosphorus to be conductive because of hole accumulation.Then,a parallel channel is activated within the strain-free graphene area by edge-contacted electrodes,thereby largely inheriting the intrinsic carrier mobility of graphene in the on-state.As a result,the device can provide an on/off voltage ratio of>10^(3)as well as a mobility of∼8000 cm^(2)V^(−1)s^(−1)at room temperature,meeting the low-power criterion suggested by the International Roadmap for Devices and Systems. | Fanrong Lin Zhonghan Cao Feiping Xiao Jiawei Liu Jiabin Qiao Minmin Xue Zhili Hu Ying Liu Huan Lu Zhuhua Zhang Jens Martin Qingjun Tong Wanlin Guo Yanpeng Liu | 2024 | National Science Review2024，11，2： | 0 |
| 11 | Experiment and calculation on seismic behavior of RC composite core walls with concealed steel truss显示文摘To improve the seismic performance of reinforced concrete core walls,reinforced concrete com-posite core walls with concealed steel truss were proposed and systemically investigated.Two 1/6 scale core wall specimens,including a normal reinforced concrete core wall and a reinforced concrete composite core wall with concealed steel truss,were designed.The experimental study on seismic performance under cyclic loading was carried out.The load-carrying capacity,stiffness,ductility,hysteretic behavior and energy dissipation of the core walls were discussed.The test results showed that the seismic performance of core walls is improved greatly by the concealed steel truss.The calculated results were found to agree well with the actual measured ones. | Wanlin CAO Weihua CHANG Changjun ZHAO Jianwei ZHANG | 2009 | Frontiers of Structural and Civil Engineering2009，3，3： | 0 |
| 12 | Lifting surface reconstruction of Au(100)by tellurium adsorption显示文摘The Au(100)surface has been a subject of intense studies due to excellent catalytic activities and its model character for surface science.However,the spontaneous surface reconstruction buries active Au(100)plane and limits practical applications,how to controllably eliminate the surface reconstruction over large scale remains challenging.Here,we experimentally and theoretically demonstrate that simple decoration of the Au(100)surface by tellurium(Te)atoms can uniquely lift its reconstruction over large scale.Scanning tunneling microscopy imaging reveals that the lifting of surface reconstruction preferentially starts from the boundaries of distinct domains and then extends progressively into the domains with the reconstruction rows perpendicular to the boundaries,leaving a Au(100)-(1×1)surface behind.The Au(100)-(1×1)is saturated at~84%±2%with respect to the whole surface at a Te coverage of 0.16 monolayer.With further increasing the Te coverage to 0.25 monolayer,the Au(100)-(1×1)surface becomes reduced and overlapped by a well-ordered(2×2)-Te superstructure.No similar behavior is found for Te-decorated Au(111),Cu(111),Cu(100)surfaces,nor for the decorated Au(100)with other elements.This result may pave the way to design Au-based catalysts and,as an intermediate step,even potentially open a new route to constructing complex transition metal dichalcogenides. | Erwen Zhang Huan Lu Wei Zhang Shuiyan Cao Yang Wang Rong Rong Ying Liu Zhuhua Zhang Ming Yang Yanpeng Liu Wanlin Guo | 2023 | Nano Research2023，16，5： | 0 |
| 13 | A unique hyperdynamic dimer interface permits small molecule perturbation of the melanoma oncoprotein MITF for melanoma therapy显示文摘Microphthalmia transcription factor(MITF)regulates melanocyte development and is the“lineage-specific survival”oncogene of melanoma.MITF is essential for melanoma initiation,progression,and relapse and has been considered an important therapeutic target;however,direct inhibition of MITF through small molecules is considered impossible,due to the absence of a ligand-binding pocket for drug design.Here,our structural analyses show that the structure of MITF is hyperdynamic because of its out-of-register leucine zipper with a 3-residue insertion.The dynamic MITF is highly vulnerable to dimer-disrupting mutations,as we observed that MITF loss-of-function mutations in human Waardenburg syndrome type 2 A are frequently located on the dimer interface and disrupt the dimer forming ability accordingly.These observations suggest a unique opportunity to inhibit MITF with small molecules capable of disrupting the MITF dimer.From a high throughput screening against 654,650 compounds,we discovered compound TT-012,which specifically binds to dynamic MITF and destroys the latter’s dimer formation and DNA-binding ability.Using chromatin immunoprecipitation assay and RNA sequencing,we showed that TT-012 inhibits the transcriptional activity of MITF in B16F10 melanoma cells.In addition,TT-012 inhibits the growth of high-MITF melanoma cells,and inhibits the tumor growth and metastasis with tolerable toxicity to liver and immune cells in animal models.Together,this study demonstrates a unique hyperdynamic dimer interface in melanoma oncoprotein MITF,and reveals a novel approach to therapeutically suppress MITF activity. | Zaizhou Liu Kaige Chen Jun Dai Peng Xu Wei Sun Wanlin Liu Zhixin Zhao Steven P.Bennett Peifeng Li Tiancheng Ma Yuqi Lin Akinori Kawakami Jing Yu Fei Wang Chunxi Wang Miao Li Peter Chase Peter Hodder Timothy P.Spicer Louis Scampavia Chunyang Cao Lifeng Pan Jiajia Dong Yong Chen Biao Yu Min Guo Pengfei Fang David E.Fisher Jing Wang | 2023 | Cell Research2023，33，1： | 0 |
