StLRB의 동적특성 연구를 위한 모델링 개발

Development of Modeling for Dynamic Response of StLRB System

This paper is about seismic performance of the StLRB(S.T.U＋PETE＋LRB) system, that is among various base isolator. A rational modeling of StLRB system has been presented that used Nllink element. We get theoretical solutions of equation of motion of the system and compared with numerical solutions using a finite element program, Thus, a verified modeling can be applied bridge structure of multi-degree-of-fredoom systems.
