구조동역학에서 과도시간응답의 효율적 계산에 관한 연구

Abstract

A time-step control scheme is proposed for the generalized-α method which is an implicit time integration method for structural dynamics. A new simple and efficient local error estimator is developed based upon the local truncation error. Using the developed local error estimator, a time stepping strategy is applied to control time steps for the generalized-α method.
