Hat Truss Trick -- Overcoming Design and Erection Challenges of a 24-Story Vertically-Hung Gravity Load System [CS4]111 S Main Street in Salt Lake City, Utah is a 24-story office building with a very unique structural system: to overcome complex site constraints, a creative design solution was invoked whereby the perimeter columns are hung from steel hat trusses cantilevering from the building core at the roof level. While this structural system is designed to be stable in its completed state, there are inherent challenges with erection sequencing, temporary support systems, and bracing that must be addressed during construction. In this session the project SEOR, the erection engineer, and the fabricator will present the challenges and the creative solutions invoked to overcome these obstacles and bring the project to a successful completion. The ideas presented in this session will highlight the importance of team collaboration between design and construction professionals to bridge the gap from design complexity through construction.
