Abstract

Part 2 of this paper presents the Refined Plastic Hinge Method (an advanced analysis also) to analyze plane steel frame with semi-rigid connections. This method can predict accurately the combined nonlinear effects of geometry (using stability functions), meterial (using Column Research Council (CRC) tangent modulus and a parabolic function for gradual yielding), and connection (using three-parameters model) on the behavior and strength of semi-rigid frames. From that, by using VISUAL BASIC, a Plane Steel Frame Analysis With Semi-Rigid Connections Program was built up. Three examples were used to illustrate the program and make comparision between rigid frame and semi-rigid frame.
