| 摘要： | Steel plate reinforced concrete (SPRC) composite shear walls, which are composed of steel columns embedded in boundary elements and an embedded steel plate in the wall web, have been used in super-high-rise buildings. When subjected to rare earthquake loads, combined tension-bending-shear actions are often generated in the shear walls of super-high-rise buildings because of the increasing demand for a greater height-width ratio. Based on quasistatic tests on seven SPRC shear walls under tension-bending loads, the seismic behavior of SPRC shear walls with various steel-content ratios and axial tension ratios was investigated. The failure mode, strength and displacement capacity, stiffness degradation, shear deformation, damping coefficient, strain, and cracking of each test specimen are presented in detail. The failure mode is divided into tension-bending failure, anchorage failure, and torsional buckling failure according to the test results. The strength, stiffness, and ductility of the SPRC shear walls were significantly reduced with an increase in the axial tension ratio. The fiber beam-column finite-element (FE) model was simulated using MSC.MARC software. A comparison showed that the FE model predicted the load-displacement relationship, stiffness degradation, and ultimate capacity with a reasonable level of accuracy. Based on the test results, a design method is proposed for predicting the ultimate strength of the SPRC shear walls under tension-bending combined loads, and recommendations for improved anchorage design are proposed. |
