本文采用柔度法分析下部为单跨两层框架的框支剪力墙结构。将总剪力墙每层处的弯矩作为基本未知量,推导出框支剪力墙结构的柔度方程组。经过局部消元变换,柔度矩阵化为三对角线型矩阵,柔度方程组化为三弯矩方程组。用追赶法在SHARP pc-1500袖珍机上求解此方程组。文中举一实例说明,其结果与SAP-84通用程序分析结果比较,两者符合较好。
In this paper, the flexural method is used to analyze the frame-supported shear wall structure with a single span and two-layer frame. Taking the bending moment at each layer of the total shear wall as the basic unknown, the flexibility equations of the frame-supported shear wall structure are deduced. After the local elimination transformation, the flexibility matrix is transformed into a tridiagonal matrix, and the flexibility equations are grouped into three-moment equations. The equations were solved on the SHARP pc-1500 Pocket Machine with chase. An example is given in the article. The results are in good agreement with the SAP-84 general program analysis results.
