为了研究夹层复合板填充钢框架的滞回性能，进行了8个足尺单隔板单层试件的低周反复加载试验。考虑了板厚度、板类型、板位置、柱方向、梁柱连接方式以及板与钢框架的连接方式等6个主要影响参数。根据试验现象、滞回曲线、骨架曲线、强度退化曲线、刚度退化曲线、延性指数和粘性阻尼系数，对板的抗震性能进行了评价。试验结果表明，板的破坏主要发生在埋藏区周围；但墙板的整体性要好于传统的墙体。墙板与钢框架的连接成功与否对保证两者共同工作尤为重要。增加墙板厚度和加强连接都可以改善结构的抗震性能。最后，基于对结构延性指标和耗能能力的分析，提出了抗震设计建议。
In order to study the hysteretic behavior of steel frames filled with sandwich composite panels(SCP),low cyclic loading tests on eight full scale one-bay,one storey test specimens were carried out.Six main influential parameters including panel thickness,panel type,panel position,column orientation,beam-to-column connection type and connecting method of panel to steel frame were considered.Seismic behaviors were evaluated according to the experimental phenomena,hysterics loops,skeleton curves,curves of strength degradation,curves of stiffness degradation,ductility index and viscous damping coefficient.Test results show that the failures of panels mainly occur around the embedded parts,but the integrity of the panels is better than the traditional walls.The success of connection between panel and steel frame is especially important to guarantee the mutual work of the two parts.Both increasing the panel thickness and strengthening the connection can improve the seismic behavior of the structure.Finally,seismic design recommendations were presented based on the analysis of ductility index and energy dissipation of the structure.
