摘要
构造一种能模拟一层框-剪结构的新型分析方法——层单元.采用杆单元法、层单元法和解析公式,分别计算不同结构刚度特征值的等刚度框-剪结构,在不同的外荷载作用下的内力和位移;采用杆单元法和层单元法,计算不同结构刚度特征值的变刚度框-剪结构,在均布荷载作用下的内力和位移.与杆单元法比较,层单元法能显著地减少输入、输出数据和计算量,计算误差小于3.5%,
The storey element is established which can simulate one storey of the frame-shear wall structure. The internal forces and displacements of the frame-shear wall structures with the constant stiffness for various rigidity characteristics under various kinds of loads are calculated by beam elements method, storey elements method and analytical formulas. The internal forces and displacements of the frame-shear wall structures with the variable stiffness for various rigidity characteristics under uniformly distributed load are calculated by beam elements and storey elements. In comparison with beam elements methods, storey elements method can remarkably reduce the volume of input and output data and calculation, the error is less than 3. 5%.
