반복 축하중을 받는 양단고정 부재의 이력거동에 관한 해석법 연구 ( A Study on the Cyclic Behavior of Fixed-Ended Member under Repeated Axial Load )

This paper describes an analytical model for theoretically predicting the inelastic Cycle behavior of fixed-ended steel members subjected to repeated axial loading. The analysis is based on the 'Plastic Hinge Method'or 'Hinge by Hinge Method' used widely in the study of elastic-plastic behavior of steel structures. In this approach, the plastic hinge is treated as a mechanical hinge with a constant value of full plastic moment Mpc. Using this analytic procedure, closed form solutions are derived by directly solving the governing differential equation in sequence. Some of the results are compared with available tests on actual tubular steel members.
