Research on Horizontal Bearing Capacity of High-Rise RC Shear Wall Arranged High-Strength Steel in Boundary Concealed Columns

Based on the plane-section assumption, the formulas of yield moment and ultimate moment are derived for calculating high-rise RC shear wall. High-strength steels are used as transverse and longitudinal steels in boundary concealed columns of the shear wall. The practical application is performed by using the formulas derived for calculating horizontal bearing capacities of four specimens, in which one specimen used ordinary-strength steel and the others used high-strength steel. Meanwhile, the numerical simulation is carried out on the four specimens by finite element method, and the results show that the horizontal bearing capacity of the shear wall increases obviously for specimens using high-strength steel in boundary concealed column, and the simulation results of finite element method are in good agreement with formula results.
