Experimental Static Resistance of Cold-Formed Steel Roof Truss Systems
Abstract
This study aims to analyze the full static resistance of full-scale cold-formed steel trusses commonly used in the industry and identify associated failure modes in order to more accurately predict dynamic response with simplified methods. Sixteen unique truss designs were tested under quasi-static loading up to ultimate failure using a mechanical testing system. Three select designs will be discussed in this thesis. A simplified finite element analysis was performed using SAP2000 non-linear analysis and compared to experimental results. Experimental results show that truss performance and absorbed energy are significantly affected by the truss configuration and thickness of truss elements. Results of this study will be used to validate advanced numerical models. The quantifiable application of system capacities will improve future designs of building systems and lead to a more safe and resilient infrastructure.
