摘　　要：文章提出了1种新型泡沫混凝土-挤塑聚苯板复合墙板(FCPW)。为了研究这些墙板对地震事件中可能发生的加载条件的响应,共设计了3种试件,分别对不同尺寸的墙板施加循环荷载研究其抗震性能。通过分析墙板滞回曲线、骨架曲线、延性、刚度退化系数等抗震参数,认为墙板抗震性能良好。试验现象和破坏机理均表明:剪切破坏是试件的破坏形式。对比试件可以看出:高宽比和试件本身强度对抗震性能影响明显,高宽比越大,延性越大,抗震性能越好;混凝土厚度越小,延性越小,抗震性能越差。研究有助于挤塑板与混凝土组成复合墙板的更新迭代,为后续研究提供参考。In this paper,a new foam concrete-extruded polystyrene composite wall panel(FCPW) is proposed.In order to investigate the response of these wall panels to the loading conditions that may occur during an earthquake event,a total of three specimens were designed in this study to study the seismic performance of the wall panels with different sizes of cyclic loads applied to them.By analyzing the seismic parameters such as hysteresis curve,skeleton curve,ductility and stiffness degradation factor of the wall panels,it is concluded that the wall panels have good seismic performance.Both the test phenomenon and damage mechanism indicate that shear damage is the damage form of the specimen.Comparing the specimens,it can be seen that the height-to-width ratio and the strength of the specimen itself have obvious effects on the seismic performance.The larger the height-to-width ratio is,the larger the ductility is and the better the seismic performance is.The smaller the thickness of the concrete is,the smaller the ductility is and the worse the seismic performance is.This study helps to update the iteration of composite wall panels composed of extruded plastic board and concrete and provide a reference for future research.
