STOREY ELEMENT FOR ANALYZING FRAME-SHEAR WALL STRUCTURES

A storey element, which can simulate one storey of the frame-shear wall structure, is established by simply summing the rigidity matrixes of the frame and wall. The internal forces and displacements of the frame-shear wall structures for various rigidity characteristics with the constant stiffness under various kinds of loads are calculated by the beam element method, storey element method and analytical formulas. The internal forces and displacements with the variable stiffness along the height under uniformly distributed load are calculated by the beam element method and storey element method. In comparison with the beam element method, the storey element method can remarkably reduce the volume of input, output data and calculation, the error is less than 8.3%.
