中文摘要：
为研究核电工程中屏蔽厂房所采用的结构形式——双钢板混凝土组合墙体的抗震性能,对不同距厚比、不同抗剪连接件形式的双钢板混凝土组合墙体进行了拟静力抗震性能试验研究。试验模型按照1/5缩尺,设计了4个双钢板混凝土组合墙体试件。通过试验,分析了组合墙体的承载力、延性、刚度及滞回特性、耗能能力和破坏特征。结果表明：随着距厚比的减小,试件极限承载力有所提高但不显著,距厚比对栓钉的断裂点是否达到构件的极限承载力有明显影响,加劲肋连接件对提高构件的极限承载力、整体刚度、延性和耗能能力效果显著;4个试件的内部混凝土开裂荷载基本相同,抗震性能良好。
英文摘要：
This paper had studied quasi-static seismic performance experimental research on different shear connector type and double steel plate concrete composite wall in order to research earthquake resistance of shield building adopted double steel plate concrete composite wall for nuclear power project. Four double steel plate concrete composite wall specimens were designed according to the one / five scale to analyze the compound wall ’s bearing capacity,ductility, stiffness, hysteresis property, energy dissipation capacity, and failure characteristics by experiments. The result showed that as the distance-thickness ratio decreased,the specimen ultimate bearing capacity improved unconspicuously but distance-thickness ratio had a significant effect on stud breaking point whether it reached component ’s ultimate bearing capacity or not. In addition,stiffener joints had a significant impact on component ’s ultimate bearing capacity, integral rigidity, ductility and energy dissipation. Moreover, four components’ internal concrete cracking loads were the same and the seismic performances were good.
