带现浇边缘构件的预制双向孔模板剪力墙受力性能试验研究

Experimental Investigation of Anti-seismic Behavior on Precast Two-Way Hollow Slab Shear Wall with Cast-in-situ Boundary Elements

提出一种新型的装配整体式剪力墙结构体系——预制双向孔模板剪力墙,进行了一片带现浇边缘构件的预制双向孔模板剪力墙和一片普通混凝土对比剪力墙在恒定轴向压力下的低周反复加载试验,研究了预制双向孔模板剪力墙的受力性能.结果表明:预制双向孔模板剪力墙沿预制空心板竖向孔洞处混凝土出现宏观竖向裂缝,墙体的破坏特征与钢筋混凝土剪力墙显著不同,可避免剪切破坏,墙体有较大的变形能力,抗震性能良好.

The pre-cast two-way hollow slab shear wall is proposed as a new type of assembled monolithic concrete shear wall. Low-cycle loading tests under constant axial force are carried out for one precast two-way hollow slab shear wall with cast-in-situ boundary elements and one contrastive concrete shear wall. The anti-seismic behavior of precast two-way hollow slab shear wall is analyzed. The test results indicate that macroscopic vertical cracks ap-peared along vertical holes of precast slab. The prefabricated wall performs different from the contrastive wall at fail-ure. The prefabricated wall is a non-brittle one. The deformation capacity that helped improve the seismic behavior is excellent.
