摘要
通过试验研究了原材料对自密实混凝土(SCC)工作性能的影响,并将配制出的SCC应用于叠合剪力墙。为了研究现浇SCC的叠合剪力墙抗震性能,进行了2片现浇SCC与2片现浇普通混凝土墙体低周反复试验,并将结果进行了对比分析。研究显示:采用免振捣SCC,浇筑过程中预制墙体与桁架钢筋连接良好且未发生偏位,墙体表面未出现裂缝;现浇普通混凝土与SCC的叠合剪力墙破坏形态相似,两者滞回曲线、耗能能力及刚度退化趋势等抗震性能指标接近;现浇SCC叠合剪力墙延性系数高于现浇普通混凝土叠合剪力墙。
Experiments were conducted to study the influences of raw materials on self compacting concrete （SCC） working performance and the prepared mixture from the experiments was used on composite shear walls.Reversed cyclic experiments on two composite SCC walls and two regular concrete walls were conducted to study their seismic performances,and the results were compared and analyzed.Results indicated that the connection between the precast wall and the truss steel bar performed well and no cracks occurred.Compared with the regular concrete wall,the composite wall was similar in failure mode,hysteretic curve,energy dissipation capacity,and stiffness degradation,but it had better ductility performance.
