Evaluation of a seismic collapse assessment methodology

This paper presents a methodology to utilize performance-based seismic design procedure for evaluating the effect of heating in lead core of isolated structures with lead-rubber bearing based on collapse assessment and seismic loss estimation. Nonlinear archetypes of conventional 4-story steel special moment resisting frame, isolated intermediate moment resisting frame with and without heating in lead core effect are compared with each other under far-field (FF) and near-field earthquakes.

In this paper, an attempt is made to examine the efficiency of an approximate incremental dynamic analysis (IDA) method to estimate the collapse capacity of conventional steel structures. To this purpose, two partially collapsed steel structures are selected. Both two structures are comprised of an ordinarymoment resisting frame systemin one direction, and a braced frame system in other perpendicular direction.
