Abstract

This paper examines the effect of plan irregularities on the progressive collapse of braced and un-braced steel structures designed in accordance with AISC (2010) and ASCE7 (2010) which are located in regions with different seismic activity. The collapse patterns of four buildings is examined and compared across seven loading scenarios using non-linear dynamic and static analyses completed as per the GSA (2013) standards. Node displacements above the removed columns and the force increase across adjacent columns, are discussed. Also, the susceptibility of columns to collapse, based on their strength and capacity, is examined and the pushdown curve and yield load factor of the structures, after column removal, is obtained and critically discussed.
