1Factors affecting the seismic behavior of segmental precast bridge columns显示文摘这张手稿讨论潜在地影响部分预制 tensioned 以后桥墩的侧面的地震反应的设计参数。墩由有通过管的同心的腱的在其它上的叠的在扔期间在片断做了的预制的圆形的生气的节片断组成。墩的最底的片断在钢试管被装入箱内提高韧性并且最小化损坏。一个 FE 模型被用来调查不同设计参数并且他们怎么影响墩的侧面的力量排水量反应。调查的设计参数作为腱收益压力的一个百分比包括了起始的 tensioning 以后压力,水泥上的应用轴的压力作为精力 dissipaters 由于 tensioning 以后,墩方面比率,构造细节,钢试管厚度,和内部低碳钢 rebar 增加了。基于介绍的数据,在它的收益应力的 40%60% 的范围的一个起始的腱压力和约 20% 水泥特征强度的水泥上的起始的轴的应力为很典型的图案是适当的。这些设计价值将阻止腱让步直到侧面的飘移角度到达约 4.5% 。改变两个的钢试管厚度,高度,或联合证明了是可以被用来在一个特定的地震地区到达目标表演水平的一个有效参数。Haitham DAWOOD Mohamed ELGAWADY Joshua HEWES 2014Frontiers of Structural and Civil Engineering2014,8,4:13

3Green managerial practices and green performance:A serial mediation model显示文摘This study examines the influence of green supply chain management(GSCM)practices and green culture on green performance in the manufacturing sector through the mediating effect of proactive environmental strategy(PES)and green product innovation(GPI).A quantitative approach was followed,and partial least squares structural equation modeling(PLS-SEM)was used for hypothesis testing.A questionnaire was used to collect data,and 663 questionnaires were included in the final analysis.Contrary to our expectations,the results showed that GscM practices do not influence green performance,whereas green culture is positively related to green performance.The results show that PES and GPI explain the relationship between GSCM practices,green culture,and green performance.PES and GPI sequentially mediated GSCM practices,green culture,and green performance.Moreover,PES and GPI significantly improved green performance.This study aims to extend the scholarly appreciation of GscM practices and the impact of green culture on green performance by examining the mediating effects of PES and GPI on these relationships.The implications and future research avenues are also discussed.Shafique Ur Rehman Hamzah Elrehail Marc Poulin Mohamed Dawood Shamout Haitham M.Alzoubi 2023International Journal of Innovation Studies2023,7,3:0
