The seismic shear capacity of I-shaped and T-shaped reinforced concrete structural walls

There are numerous shear walls with flanges in the high-rise buildings in P. R. China. The shear strength formula for shear walls in Chinese design codes lacks experimental data, while test results in other nations lack aseismatic shear strength test results for shear walls with flanges under axial force. In this paper, we report low-cyclic reverse load test results of shear wall models with large dimensions, one shear wall having an I-shaped cross-section and two with a T-shaped cross-section. We discuss why the aseismatic shear walls of high-rise buildings with large height-to-length ratios have small shear span ratios. We assess the reliability of the shear strength formulary in the Chinese codes for design of shear wall using the international shear wall test results.
