钢管混凝土边缘约束叠合剪力墙抗震试验研究
Experimental Study on the Seismic Behavior of Concrete Filled Tube-confined Sandwich Shear Walls
摘要
Abstract
To study the seismic performance of a new concrete filled tube-confined sandwich shear wall (CFT-SSW), cyclic loading tests were carried out on three CFT-SSW specimens with different depth-thickness ratios and one conventional concrete shear wall specimen for comparison.The load-carrying capacity, ductility, stiffness and their degradation, hysteretic and energy dissipation characteristics, and failure modes of the specimens were investigated and compared.Equations for prediction of the strength of CFT-SSWs were also proposed.The calculated strengths were in good agreement with the test results.The results show that CFT-SSWs exhibited both the high lateral stiffness and strength due to reinforced concrete shear walls and the superior ductility due to concrete filled tubes.The strength, ductility, and stiffness of CFT-SSW specimens were greater than those of the cast-in-situ concrete shear wall specimens.In addition, the depth-thickness ratio has only marginal effects on the seismic behavior of the CFT-SSWs within the test range of the current tests.关键词
