【摘要】 为了解新型3D板墙体构件的抗震性能及其影响因素,通过对3片新型3D板墙体进行低周反复加载试验,获得试件的破坏特征、承载力、荷载-位移滞回曲线以及荷载-应变曲线等,研究该类墙体的承载能力、变形性能和耗能能力。试验结果表明:新型3D板墙体结构受力性能良好,整体性较强,具有良好的延性性能和耗能能力。高宽比和墙端构造对墙体的抗震性能具有较大影响。高宽比较大时,地震作用时墙体趋于发生弯曲破坏,对提高结构延性,增强结构耗能能力,改善结构抗震性能具有重要作用。通过采取墙端构造措施,可以有效提高墙体整体刚度、承载能力、延性和耗能能力,有利于结构抗震,但对延缓墙体裂缝出现作用不大。更多还原

【Abstract】 To investigate the anti-seismic performance and its affecting factors of new type 3D-wall,the failure process,bearing capacity, load-displacement hysteretic curve and load-strain curve of specimens were obtained by the quasi-static test of three new type 3D-walls. The carrying capacity,formability and energy dissipation capacity of the wall were analyzed. Experiment results indicated that new type 3D-wall is of good ductility and energy dissipation capacity. Depth-width ratio and structural measure in the end of the wall are the major influence factors on the anti-seismic performance of the walls. The flexural failure is more likely to observe in the wall with large aspect ratios,which increases the ductility and energy dissipation capacity of structure. Structural measure in the end of the wall can effectively increase stiffness,carrying capacity,ductility and energy dissipation capacity of the wall,but it has a positive effect for delaying the appearance of cracks.更多还原
