摘要:
为研究钢结构仿古建筑带斗檐柱的延性和刚度退化规律,对其进行了低周反复荷载试验,分析了试件的受力过程和破坏形态,同时,研究了试件柱端P-Δ滞回曲线和水平荷载 - 应变曲线,研究了其延性和刚度在加载过程中的变化规律.结果表明:试件长细比对其延性影响较大.当采用同一轴压比数值时,试件延性随着长细比数值的增大而越高,塑性变形能力越强; 试件长细比对其刚度退化影响较大,当轴压比数值一定时,试件刚度退化速率随其长细比数值的增大而逐渐降低,破坏时柱转角也随之减小.反之,试件刚度退化速率增大,试件破坏时,柱转角增大.
Abstract:
In order to study the ductility and stiffness degradation characteristics of eave columns with corbel brackets in steel archaized buildings, the low-cycle repeated load test was carried out on the steel structure antique building with bucket column. The P-Δ hysteresis curve, horizontal load-strain curve, stress process and failure mode of the specimen were analyzed. The variation of ductility and stiffness during the loading process was studied.Results show that the slenderness ratio of the specimen has a great influence on the ductility. When the same axial compression ratio is used, the ductility of the specimen increases with the increase of the slenderness ratio, and the plastic deformation ability is stronger. The slenderness ratio of the specimen has a great influence on the stiffness degradation.The rate of degradation of the specimen gradually decreases with the increase of the ratio of the slenderness ratio, and the corner angle of the column also decreases. On the contrary, the rate of stiffness degradation of the test piece increases, and the column rotation angle increases when the test piece is broken.
