    摘要
  • 摘要: 为分析脱硫石膏砌块填充墙体对新型装配式钢框架抗震性能的影响，开展了2榀1/2缩尺的单跨2层装配式钢框架的拟静力试验研究。通过与纯钢框架试件的对比，得到了脱硫石膏砌块填充墙体的破坏模式及其对钢框架抗震性能的影响。结果表明：采用新型装配式节点的钢框架具有良好的抗震性能；脱硫石膏砌块填充墙体不仅显著提高了框架的初始抗侧刚度，而且对框架的延性、耗能均有不同程度的提高。采用数值建模的方法对试验进行模拟，其结果与试验结果吻合良好，并针对试件的轴压比、高跨比和砌块厚度进行变参分析，得出增大试件的轴压比对试件的延性有一定的削弱作用，建议轴压比取值小于0.4；过大或过小的高跨比对结构均不利；改变砌块厚度对结构初始刚度影响较大，但对结构的承载能力影响较小。
    Abstract: In order to analyze the effect of desulfurized gypsum block filling wall on the aseismic performance of a new fabricated steel frame, we carried out the quasi-static test of a single span 2 layer fabricated steel frame with 1/2 scale and obtained the failure mode of masonry block filled wall. Compared with a steel frame, we obtained the statistics about effects on the aseismic performance of a steel frame and concluded that:the steel frame with new assembly joints has good aseismic performance; the presence of desulfurized gypsum block filled wall increases the initial stiffness of the frame and the ductility and energy dissipation of the frame. Additionally, numerical modeling is used to simulate the experiment, and the results are in a good agreement with the experiment. The parameter analysis of axial compression ratio, high span ratio and block thickness of specimens were also conducted. The data of these suggest that:the compression ratio of the specimen has a certain weakening effect on its ductility, the recommended axial pressure ratio is less than 0.4; too large or too small of the high span ratio structure is unfavorable, changing the thickness of block has a great influence on initial stiffness, but it has little effect on the bearing capacity of the structure.
