Calculation Method Research of Shear Bearing Capacity for Frame-Sparse Gridiron Composite Wall

Article Preview

Abstract:

In order to enhance the anti-seismic performance of the frame structure and masonry structure with frame at bottom layer, combined shear wall consisting of frame and gridiron composite wall was proposed in this paper, and shear bearing capacity calculation method for the wall was researched. 1/2 scale frame-sparse gridiron composite walls were tested under reversed cyclic loading. Damage processes, load-bearing capacity and hysteretic curves characters of the walls were analyzed. Based on the experiments and reinforced concrete masonry walls data, the force features and shear resistance mechanism of the wall were analyzed, and general shear bearing capacity formula were put forward, and application methods under different conditions were given at the same time. Comparative analysis between calculation results and test results indicated that the formula was accurate enough, and can be referred to in the new construction and post-quake reconstruction of frame structure or masonry structure with frame at bottom layer.
