Abstract
This paper considers the robustness of prototype 10-story steel moment-frame and braced-frame buildings. Reduced modeling approaches are presented for steel moment-frame and braced-frame buildings with composite floor slabs, and these approaches are used to analyze the nonlinear system behavior of these types of structures under column loss scenarios. The three-dimensional reduced structural models include the composite floor slab and incorporate assemblies of nonlinear spring elements to represent the beam-to-column connections. For the braced-frame buildings, modeling of the buckling behavior of braces incorporates nonlinear rotational springs representing the out-of-plane behavior of the gusset-plate connections. Analysis results are presented, and the behavior of braced frame and moment frame buildings under column loss is compared.Proceedings Title
