新型装配-现浇式密柱结构体系抗震性能试验研究
Test study on seismic behavior of new structure with assembly-situ wall
【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.
【Abstract】 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 condition 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 bearing 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.
