为研究板壁式型钢混凝土柱在低周反复荷载下的破坏性能,本文以长细比和轴压比为主要变化参数,对3个试件模型进行低周反复加载试验,重点研究了不同长细比和轴压比下板壁式型钢混凝土柱的破坏过程和破坏形态、试件应变情况、延性,并提出了板壁式型钢混凝土柱的水平极限承载力计算公式。
In order to study the failure performance of the slender steel reinforced concrete (SRC) columns under cyclic low cyclic loading, the slenderness ratio and axial compression ratio were taken as the main parameters to carry out low-cycle cyclic loading tests on the three specimens. The ratio of axial compression ratio and the ratio of axial compression ratio, the failure process and the failure mode of slab steel reinforced concrete columns, the strain and ductility of the specimens, and the formulas for calculating the horizontal ultimate bearing capacity of slab-type steel reinforced concrete columns are proposed.
