Numerical Performance Assessment of Modular Two-Way Precast Slab Systems

The overarching goal of this partnership is to develop a modular accelerated building construction system that is suitable for implementation into the Canadian marketplace. The use of the post-tensioned, and friction-based, connections for modular system connections is atypical of North American design procedures and the reliance on these connections for resisting sustained gravity loads is generally not supported in existing Canadian building design standards. This research will critically examine the structural performance of such friction-based post-tensioned modular connections and will develop alternative post-tensioned RC connection details that incorporate desired redundancies. These findings will be used to develop system level models to assess the performances of buildings constructed using modular construction technologies. Research outcomes in the form of demonstrable and response-adequate structural performance characteristics for alternative modular building system connection details will enable Envision Integrated Building Technologies to introduce new cost-effective building construction technologies in Canada.
