Analytical Modeling Method of Beam-Column Joints for the Inelastic Analysis of R/C Structures

철근콘크리트 구조물의 비탄성해석을 위한 보-기둥 접합부의 해석모델링 기법

The purpose of this paper to describe an analytical model that is capable of reproducing the hysteretic behavior of beam-column joints under cyclic loading and to suggest the variable of hysteretic model for the inelastic analysis of R/C frame structures to do this quasi-static analysis using IDARC program was performed for the beam-column joints. The effort to obtain the result of analysis similar to those of experiment was made by determining the value for hysteretic parameters representing stiffness degradation, strength deterioration and pinching effect. The accuracy and reliability of the proposed analytical model was demonstrated by comparison of load-displacement relation, maximum strength, stiffness degradation and energy dissipation.
