摘要:
某超高层建筑巨型框架采用了直角梯形截面型钢混凝土巨型柱,为研究这种不对称截面型钢混凝土巨型柱的抗震性能及混凝土强度对抗震性能的影响,进行了2个较大尺度的不同混凝土强度的直角梯形截面型钢混凝土巨型柱模型的低周反复荷载试验。比较了2个试件的水平承载力、滞回性能、骨架曲线、刚度、耗能及变形,分析了正、负两向加载下试件抗震性能的差异及混凝土强度对试件抗震性能的影响,采用条带法对试件正截面承载力进行了计算。结果表明:两试件均呈现以弯曲为主的破坏形态,滞回曲线均较饱满,滞回耗能性能良好;由于试件截面配钢和配筋不对称、骨架曲线不对称,正向加载下,截面直角边基本均匀受压,抗震性能相对好,负向加载下,截面斜边尖角部位受压较大,抗震性能相对差;混凝土强度较高的试件,滞回曲线更为饱满,水平荷载达峰值前刚度退化较慢,表现出了良好的抗震性能,但达到峰值点后承载力下降相对快些;用条带法计算所得正截面承载力与试验符合较好;构造合理的直角梯形截面型钢混凝土巨型柱可用于巨型柱框架抗震设计。
Abstract:
Right-angle trapezoidal section steel reinforced concrete (SRC) mega columns are applied in the mega frame of a super high-rise building. In order to investigate the seismic behavior of the asymmetric-section SRC mega columns and the influence of concrete strength on their seismic behavior, low cyclic loading test was carried out on 2 large-size right-angle trapezoidal section SRC column specimens with different concrete strength. The horizontal bearing capacity, hysteretic performance, skeleton curves, stiffness, energy dissipating ability and deformation are discussed and compared. The difference of the 2 specimens’ seismic behavior under positive and negative loading direction and the impact of concrete strength on seismic behavior are analyzed. The strip method is utilized to calculate the bearing capacity. Results show that both specimens are observed bending-based failure modes, the hysteretic curves are full, and the energy dissipation performed well. As the section, steel, and reinforcement of the specimens are asymmetrical, the skeleton curves are asymmetrical as well. The seismic performance is relatively good when the right angle of the section is in the compression under the positive loading direction. The sharp corners of the section are under great pressure, which leads to a relatively poor seismic performance under negative loading direction. The specimen with higher concrete strength is observed a fuller hysteretic curve, slower stiffness degradation before the horizontal load reaches the peak point, and a good seismic performance. However, the bearing capacity declines relatively quickly after reaching the peak point. The calculated value of the strip method matches the test results well. The results suggest that right-angle trapezoidal section SRC mega columns with proper configuration can be used in seismic design of mega frame structures.
