EVALUATION METHOD FOR THE RESTORING FORCE CHARACTERISTIC OF THE REINFORCED CONCRETE MULTI-STORY SHEAR WALLS : A study on the evaluation method for the earthquake resistant performance of the reinforced concrete multi-story shear walls (Part 1)

Abstract

For the design based on the performance, the evaluation method for the earthquake resistant performance of the reinforced concrete multi-shear walls is being developed. In this paper, the evaluation method for the restoring characteristic of the multi-story shear walls, which is developed originally is described. The main characteristics of this method are following; 1) the whole deformation consists of the bending deformation and the shear deformation. 2) the evaluation method for the shear deformation is based on the truss theory which considers the normal force, the restraint effect by the outline frame and the effect by the bending yield. The calculated results by this method corresponded well to the experimental results.
