Simple Linear Elastic Static Analysis Procedure To Attain Desired Collapse Mechanism for Moment Resisting Frames
Abstract eng: Considerable differences exist in current code provisions on the required (flexural) column-to-beam strength ratio (CBSR) at a joint to ensure that ductile flexural hinges occur at beam ends prior to that in columns (and joint). A simple procedure is proposed using results of linear elastic static analysis, adhering to strong-column weak-beam (SCWB) design philosophy, which leads to desired inelastic behavior of moment frame buildings during strong seismic action. The proposed procedure utilizes the ratio of elastic demand, determined just prior to the formation of first hinge, and over strength flexural capacity at all beam column joints. This procedure guides the designer to arrive at the required relative strengths at each joint of the building.
