INVESTIGATION OF PRACTICAL GEOMETRIC NONLINEAR ANALYSIS METHODS FOR SEMI RIGID STEEL PLANE FRAMES

Abstract

In this study, various practical geometric nonlinear analysis methods which encompass both the member stability (P-o) and frame stability (P-~) are investigated for different types of semi rigid beam-to-column connections. Odd power polynomial function is used for the moment-rotation relationships and beam-tocolumn connections are modeled with rotational flexible springs. In order to capture the P-deIta effects of ach beam-to-column connection, a numerical study of a six storey one bay steel plane frame is used and the results for lateral storey drifts, end moments are summarized in tables and graphics.
