摘要
利用QR法的基本原理构造出一组新的B样条基函数,并与幂级数结合,建立了结构位移函数.按照剪力墙受力特点选择了适当的本构模型,将QR法引入结构的弹塑性分析中,并采用增量初应力迭代法建立了新的计算格式.编制了剪力墙结构的弹塑性分析程序,且利用它对一联肢剪力墙结构进行了分析,计算结果与ANSYS有限元分析结果对比表明:该方法适应性强,未知量少,精度高,计算简便.
According＇to The principles of QR method, the new spline basic function was deduced. Combining it with power series, the paper worked out the displacement function. The proper constitutive model is selected according to the mechanical properties of shear walls. Introducing QR method to elasto-plastic analysis, the new computing format is built by the incremental iterative method for initial stress. The program is designed for elasto-plastic analysis of shear walls, and an actual model of coupled shear wall is analyzed with it. By compared with ANSYS, the results show that QR method has gathered some merits of strong adaptability, few variables, high precision and simple computation.
