Seismic Behaviour of SPRC Cutting Walls With Different Steel Content and Axial Stress Ratios

Abstract

Steel plate reinforced concrete (SPRC) composite shear walls, which are made out of steel sections embedded in limit elements and an embedded steel plate in the wall web, have been utilized in super-elevated structures. When exposed to uncommon quake loads, combined tension-bending-shear activities are frequently created in the shear walls of super-elevated structures in light of the increasing demand for a more noteworthy tallness width ratio. In light of semi static tests on seven SPRC shear walls under tension-bending loads, the seismic behavior of SPRC shear walls with different steel-content ratios and axial tension ratios was investigated. The failure mode, strength and relocation capacity, stiffness degradation, shear deformation, damping coefficient, strain, and cracking of each test example are presented in detail. This paper showed that the FE model predicted the heap uprooting relationship, stiffness degradation, and extreme capacity with a healthy degree of precision. In light of the test outcomes, a design strategy is proposed for predicting a definitive strength of the SPRC shear walls under tension-bending combined burdens, and proposals for improved anchorage design are proposed.
