摘要
做了3个陶粒砼框架顶层边节点抗震性能试验。试件在其它条件相同的情况下采用3种不同的负弯矩筋搭接方案,在低周交变荷载下观测试件破损特点,发展过程及最后破坏形式,测定钢筋应变规律和荷载一位移滞回曲线。对采用不同负筋搭接方案的陶粒砼框架顶层边节点的工作机理及抗震性能做了分析评价。
Earthquake resistant testing of 3 sand-haydite concrete fram's joints was made and its results are presented here. The variable of samples is lap scheme of reinforcement only. The testing purpose is to observe the sample's failing characteristic, cracking process and its last failing condition as well as to obtain the regularity of reinforcement's strain and load-displacement curve. Based on the testing results, the failing mechanism and the earthquake resistant properties were studied.
