Experimental Study on Aseismic Characteristics of RC Shear Walls with Diagonal Profile-Steel Bracings

摘要

This paper focuses on an experimental investigation and theoretical analysis of different types of RC shear wall the profile steel strengths in two side columns and diagonal profile steel braces of walls subjected to applied repeated cyclic loads. Fifteen RC shear walls with different shear span ratio are tested and their aseismic charactertics are studied. The effect of profile steel bracings on failure property, bearing capacity, ductility and hysteretical characteristic of shear wall is investigated based on experimental results. It is shown that adding the profile steel braces on the boundary column and inner of walls can obviously enhance the ultimate strength of specimens and improve their aseismic characteristics.
