摘要
本文在应用多垂直杆单元的基础上 ,提出了一种能反应剪切刚度随垂直杆拉压刚度变化的简化模型 ,这一模型与实际结构受力更加符合。该模型可直接用于小开洞剪力墙的分析 ,结合分段变刚度单元 ,分析了大、小开洞剪力墙的非线性地震反应。最后 ,提出了一个算例 ,并与试验结果比较 。
Based on application of the parallel multi?component, this paper adopts a simplified model that can reflect the interaction between the axial stiffness and the shearing stiffness of the vertical elements which will conform to the real action of the structure . This model may be used to analyze shear wall with small holes. Combined with element model with varied stiffness in different regions , nonlinear seismic response of shear wall with large or small opening holes was analyzed. Finally, an example was calculated and compared with test results , which shows that the model has relatively good accuracy.
