Description: Extensive testing has been carried out at McMaster University towards the modelling of complex masonry structures and system behaviour through use of 1/3 scale concrete block units.
Keywords: Seismic, Shear Walls, Boundary Elements, Dynamic Loads, McMaster University

Lead Investigators: Wael El-Dakhakhni (McMaster), Robert Drysdale (McMaster)
CMRC Support: CMRC members have provided support through the donation of a Commercial Grade Block Machine as well as through the funding and supervision of NSERC Industrial Postgraduate Scholarships (IPS) and the provision of mason time. Continued support is also offered through the formation of the Martini, Mascarin and George Chair in Masonry Design at McMaster University.

- NSERC IPS Student Musafa Siyam (Seismic performance parameters of slender and squat reinforced concrete masonry)
- NSERC IPS Student Ahmed Ashour (Slab coupling effects on the seismic response of reinforced masonry buildings)
- NSERC IPS Student Mohamed Ezzeldin (Seismic performance of coupled reinforced masonry shear walls with boundary elements)
Impacts of Research: Results generated from this project will help to quantify the behaviour of masonry structures and enable designers to take advantage of aspects of wall coupling and gain a better understanding of system-level seismic performance.
