Experimental and numerical investigation into the seismic performance of vertical connections used in precast concrete shear walls

Precast concrete shear walls are an economical structural system for low, medium, and high-rise buildings. Precast concrete structural systems have various advantages, such as improved quality of construction, efficient use of materials, reduced construction time, and cost-efficiency. The concrete wall panels are typically one story in height and are connected horizontally and vertically to adjacent panels at each story. This research focuses on investigating the behaviour of typical vertical connections, currently designed, fabricated, and installed by Advance Precast Ltd. (AP), under earthquake loading conditions. A range of connections will be evaluated experimentally with different shear and tension loads. The experimental result will be used to calibrate a numerical model. This model will be used to evaluate a broader range of configurations. The outcome is a design procedure for these typical vertical connections. Then, improved vertical connections will e developed based on deficiencies found in existing connections. The improved connections will undergo a rigorous experimental and numerical program like before. The outcome will be more efficient and robust vertical connections, which may be used to assemble precast concrete shear walls in higher seismic regions in Canada.
