摘　　要：用等代框架法计算板柱结构的关键是确定等代框架的宽度。为得到带边梁板柱结构的等代框架宽度取值系数的计算公式 ,用SAP91有限元计算程序对 5组 33种不同几何参数的板柱结构进行了计算 ,以研究结构几何参数对等代框架宽度取值系数的影响 ,并与钢筋混凝土板柱结构的振动台试验结果进行了对比。结果表明 ,所提出的公式具有较高的计算精度。The equivalent frame method is the most common method for flat\|plate structures, and how to compute the equivalent frame width coefficient is one of core questions of the method. In order to get the formulas for calculating the equivalent frame width coefficient of flat\|plate structures with edge beam, the structural program SAP91 was used in the elastic analysis of flat\|plate structure to study the internal relationship between the equivalent frame width and the structure dimensions. The calculated results agree well with the shaking table test results of reinforced concrete flat\|plate structures.
