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.
