摘要
为提升新型装配-现浇式密柱结构的抗震性能,通过对2榀模型在低周反复荷载作用下的试验分析,研究了其在正常使用阶段和承载极限状态时墙体各截面应力、裂缝、变形、破坏形态及延性性能.结果表明:结构在正常使用荷载作用下具有良好的延性及变形能力,抗震性能明显优于普通剪力墙;预制外壳与现浇柱联结性能良好,不会出现滑移错动;预制外壳的增加能显著提高结构承载性能,采用"最优尺寸"的截面设计能更好地发挥结构抗震能力.新型结构具有良好的整体工作性能,可以作为抗震房屋建筑的结构体系.
To improve the seismic performance of new structure with assembly-situ wall, quasi-static experiments were applied to two models. The stress, cracks, deflection, failure patterns and ductility were separately studied in normal and ultimate stage. Results indicate that under normal work condi- tion the structure displays superior ductility and deformation capacity than ordinary shear wall. In addition, the connection between precast shell and cast-in-situ columns is excellent relative is excellent without any relative glide. The precast shell can significantly improve beating properties; meanwhile the ＂optimal size＂ section has capability to promote seismic capacity. In conclusion, the new structure displays stable performance as a whole, which can be applied as structure for anti-seismic building.
