Collapse Analysis of Moment Resisting Steel Frame Using Force Analogy Method
In this paper, collapse analysis (via Incremental Dynamic Analysis, IDA approach) of moment resisting steel frame has been conducted using Force Analogy Method (FAM). FAM is an algorithm which uses consistently the stiffness matrix developed initially in performing the whole nonlinear analysis, thereby cutting down the computational time, as compared to traditional finite element method. As a result of the analysis, it has been seen in general that storey-wise IDA curves at 40% building height becomes more critical at lower scale values (i.e. lower than 1.0) of ground motion amplitudes. For higher scale values (i.e. greater than 1.0) of ground motions amplitudes, initiation of collapse has been seen for the building frame and ground motions considered.
