Application of Experimental Results to Computational Evaluation of Structural Integrity of Steel Gravity Framing Systems with Composite Slabs
Publication: Journal of Structural Engineering

Abstract
The simplicity of steel gravity framing systems in their load paths and construction has led to questions regarding their structural integrity or robustness. When considering structural integrity, the problem is often framed around the concept of column-removal scenarios, in which the structure must develop alternate load paths. The sometimes prohibitive space and resource requirements for experimental evaluation of steel gravity framing systems subjected to column-removal scenarios have resulted in the development of computational approaches to the problem. Recent computational research on this topic has highlighted the importance of considering the contribution of the composite slab to system robustness. A shell-based composite layup strip approach is the current state of the art for representing the composite slab in computational models. However, this approach has not been fully validated with experimental data and contains inherent assumptions, such as continuity of the metal deck between bays, that may not reflect construction realities. This study uses the results of experimental component level tests of the composite slab to evaluate those assumptions at the material, component, and system levels of modeling.
