YIELD DISPLACEMENT EVALUATION OF RC BUILDINGS EXAMINED BASED ON SHAKING TABLE TEST

Yield displacement is an important parameter that is directly used in computing damping factor of buildings in the Capacity Spectrum Method. In this paper, an evaluation method of a yield displacement of a building is firstly developed so that it can quantitatively consider hysteresis energy absorption characteristics of structural components. The proposed method is, secondly, examined based on a shaking table test of an 80% scale 5-story RC frame specimen to find the hysteresis damping factor of the specimen estimated following the proposed method can have a good agreement with those obtained based on Sa – Sd hysteresis test results.
