摘要:
为研究带栓钉的内置钢板混凝土剪力墙的受力状态及承载力的变化规律，以4 个带栓钉的内置钢板混凝土剪力墙试验研究为基础，采用有限元软件ABAQUS 建立了22 组带栓钉的内置钢板混凝土剪力墙的有限元模型，模拟了加载的过程和剪力墙的受力性能，考虑了材料的非线性，栓钉的滑移模型等，并将模拟结果与试验结果进行对比.分析不同参数如墙体厚度，钢板厚度，栓钉的直径、间距，轴压比及高宽比对组合墙的水平承载力和变形的影响，主要得到了栓钉对内置钢板混凝土剪力墙的影响规律.分析结果表明：当墙体、钢板厚度满足一定要求时，采用较大直径栓钉可以明显提高墙体的抗剪承载力，但随着栓钉直径的增大，承载力增加减慢；加密布置细直径栓钉后剪力墙承载力提高明显，而且延性较好.通过栓钉的模拟计算，拟合了带栓钉的内置钢板钢筋混凝土剪力墙的受剪承载力公式，可为设计应用提供理论依据．
Abstract:
To research stress state and the variation of shear capacity, based on the experiment of 4 embedded steel plate concrete shear walls with arrayed studs, a total of 22 finite element models were designed to simulate the process of the loading and concrete walls mechanics behavior by ABAQUS. The nonlinear behavior of materials, load-slip behavior and fracture model of studs are taken into account in the analysis. The reliability of the finite element model was verified through the comparison of analysis results with experimental results. Based on the proposed model, the combination of the following parameters were varied so as to compare their influence on structural response of the walls: the thickness of the concrete wall, the thickness of steel plate, stud diameter, spacing, axial load ratio and the aspect ratio. The results of the analysis about different parameters mainly show the variation of the bearing capacity of the shear wall with studs. When concrete wall and steel plate thickness meet the basic demand of details，shear bearing capacity is obviously improved by using bigger diameter studs. However, shear bearing capacity increases slowly with the increase of the diameter stud. Shear bearing capacity and ductility of shear wall become stronger by decreasing the span of studs. Considering the studs, the formula for calculating maximum shear capacity of embedded steel plate concrete shear wall with arrayed studs is also suggested. According to the simulation results, this formula provide a reference for engineering design.
