상.하부 ㄱ형강 접합부의 초기회전강성 해석모델 / An Analytical Model for the Prediction of the Initial Stiffness of an Unstiffened Top and Seat Angle Connection

초록

A top and seat angle connection can be classified by its seat angle connection type and by double angles connected to the web of a beam. In general, the top and seat angle connection has been usually designed by an assumption such that a seat angle resistsalmost the entire shear, on the other hand, a top angle promotes the stability of the connection. In order to such top and seat angleconnection behaves properly, it should have enough stiffness and strength. Therefore, this study has been conducted to establish thevariation of the initial stiffness and to propose an analytical model by varying top angle thickness and bolt gage distance. The analyticalmodel has been proposed on the base of the results of finite element analysis and its applicability has been verified by comparing resultswith those obtained by other research.
