Abstract

Braced frames and roof trusses may interfere with functional spaces in multi-story, portal-framed structures. This research explores the application of a deployable mechanism as part of the structure to enhance the performance of multi-story buildings. The work presented herein involves simulation of a 3D, scaled-down, aluminum-framed, deployable truss roof-braced frame system. The authors propose this new structural system for prototype structures, incorporating actuator-controlled mechanisms for significant shape changes leading to a topology change. The resulting deployable structural system is sleeker, utilizing less space, material, and energy than traditional structural forms to resist lateral and gravity loads.
