AN APPROXIMATE VIBRATION ANALYSIS OF FRAMES HAVING MULTI-STORY SHEAR WALLS

Abstract

This paper proposes a new approximate method for vibration analysis of frames having multi-story shear walls by reducing the degree-of-freedom and nodes in finite element model. The proposed method is based on applying the displacement function for reducing the nodes of shear walls in the model and the reduction of dynamic matrices. Finite element models reducing the degree-of-freedom and nodes by the method are analyzed. In conclusion, the analyzed results of the deformation and member forces of the model are approximate to the exact solutions. The proposed method can be applied as an approximate method of analysis for the three-dimensional vibration of buildings.
