摘要
为研究组合式烧结隔墙板-钢筋混凝土框架的抗震性能,对一榀采用柔性连接的组合式烧结隔墙板-钢筋混凝土框架进行了低周反复荷载抗震试验,分析荷载-位移曲线、刚度退化曲线、延性系数等。试验结果表明:当烧结隔墙板与钢筋混凝土框架采用柔性连接时,可有效避免墙板在加载初期的破坏,随着框架变形的增大,墙板对框架起到斜撑作用,有助于提升框架的整体抗震性能,使组合式烧结隔墙板-钢筋混凝土框架结构整体呈现良好的耗能能力和延性。
In order to study the seismic behavior of composite fired wall boards reinforced concrete frame,the low cycle repeated loading test was carried out for the composite fired wall boards-RC frame structure.Experiment phenomena,load-displacement curves,stiffness degradation curves and displacement ductility factors were given.The results showed when the fired wall boards is flexibly connected with the reinforced concrete frame,it can effectively avoid the destruction of the wall board at the initial stage of loading.With the increase of the deformation of the frame,the wall board acts as a slant support to the frame,which helps to improve the overall seismic performance of the frame,and makes the composite fired wall board reinforced concrete frame structure show good energy dissipation capacity and ductility as a whole.
