반복하중을 받는 철근콘크리트 부재의 비선형 해석모델 ( A Nonlinear Analytical Model of R/C Elements Subjected to Repeated Loads )

The purpose of this study is to propose the model with can produce hysteretic behavior load-displacement curve. This model consists of the physical single component model of R/C members together with its hysteretic rules which can idealize the behavioral characteristics of each members. This study confirms the accuracy of the proposed nonlinear analysis model through the comparision with the test results performed on R/C elements having a variety of geometric and material properties. This study is based on the fact that deformation of R/C members is composed of bending, shear and fixed-end displacement at the beam-column joints under cyclic loads.
