000018600 520__ $$2eng$$aThe behavior of a four-story steel special moment frame (SMF) subjected to various levels of seismic excitation is investigated computationally. The frame employs deep column sections designed in accordance with current design criteria. The structural system is represented by a detailed finite-element model, validated using available experimental data and capable of accounting for the influence of local buckling as well as lateral torsional buckling behavior of the steel columns. The effect of: 1) three different laterally braced conditions for the columns, and 2) three different levels of gravity load on the collapse response are parametrically investigated. It is shown that when the gravity axial load ratios are larger than 20% of the yield capacity, the columns become significantly more susceptible to severe local and global buckling, which can lead to vertical progressive collapse.
