双钢板混凝土组合剪力墙轴压承载力研究
Study on axial compressive bearing capacity of composite shear wall with double-skin steel plate
摘要
Abstract
This study conducted a steel-plate buckling analysis and a stress analysis of confined core concrete in a composite shear wall with a double-skin steel plate. Using the bottom shear wall of a core tube in the Beijing Chinese Statue as a prototype,the study tested the 1/4-scale concrete composite shear wall with a double-skin steel plate and a composite shear wall with an embedded steel plate with respect to axial compression, and then compared and analyzed the axial bearing capacity and load-displacement curves. Considering the influence of steel-plate buckling on the axial bearing capacity and the improved compressive strength of confined con-crete,this paper proposes a calculation formula for the bearing capacity of a composite shear wall with a double-skin steel plate. Com-paring this calculated values with those of other methods,the calculated values of this proposed method fits best. Based on relevant da-ta in the literature regarding axial compression performance tests of composite shear walls with a double-skin steel plate,the axial com-pressive bearing capacity values obtained by this proposed formula are in good agreement with experimental results.关键词
