エンドクロニック理論による鉄筋コンクリート部材の地震応答解析

Abstract

In this paper, the applicability of a new inelastic analytical procedure of reinforced concrete based on endochronic theory is discussed. The behaviors on inelastic response of reinforced concrete members subjected to earthquake groung motions are investigated. Main results are summaraized as follows : 1) The stress-strain relations predicted with the endochronic theory proposed by Z. P. Bazant et al. are applicable to the predictions of the dynamic response of reinforced concrete members. 2) The responses of reinforced concrete member subjected to earthquake ground motions are very affected by the slippage between longitudinal steel bar and concrete. 3) The coupling effects of two-dimentional external forces for the dynamic response of reinforced concrete member are cleary noticed, in the region that the reinforced concrete member is unstable.
