单跨多层外悬挑式框架结构校舍抗震性能试验研究
|
摘要
以典型单跨多层外悬挑式钢筋混凝土框架结构校舍为原型,按照1:3缩尺比例设计了一榀单跨框架试验模型,并进行了抗震性能试验研究,分析了单跨框架的变形能力、滞回性能、承载能力、延性系数、刚度退化、耗能能力等力学性能,试验结果显示单跨框架破坏模式为近悬挑端"强柱弱梁"型破坏,远悬挑端柱塑性铰破坏。
Referring to the typical multi-storey single-span RC frame school buildings with single cantilever corridor,a model was made in the ratio of 1:3.Then the low cyclic loading experimental study was made and the deformability,hysteretic behavior,bearing capacity,ductility factor,stiffness degradation,energy dissipation capacity of the structure were analyzed.The experimental results showed that the failure mode of the singlespan RC frame structure was strong column-weak beam near the single cantilever corridor and failure of column hinge far away from the single cantilever corridor.
