鉄筋コンクリート柱の崩壊変形に関する研究

Abstract

This study is intended to grasp general nature of column collapse. Half-scale model specimens with shear or flexure-shear failure modes simulating RC columns designed by the old code were tested until they came to be unable to sustain axial load. Test variables were longitudinal reinforcement, axial load and transverse reinforcement. Using results from this test and past tests, the general nature of column collapse, especially lateral drift associated with collapse is discussed. Some structural indices that are considered to govern the amplitude of collapse drift are also discussed.
