摘要
En 中文
In this paper, a new classification system for steel beam-to-column connections in an unbraced frame is devised demarcating the moment-rotation diagram into three connection zones by two smooth nonlinear lines. The equations of these two nonlinear lines are taken from a three-parameter moment-rotation model. The three parameters used in the model are: initial connection stiffness R-ki; ultimate moment capacity M-u of connection; and a shape parameter n. It was observed that the proposed classification system is simpler and more accurate than the existing classification systems. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
