Ultimate Drift Capacity of Flexure-Dominant Reinforced Concrete Masonry Shear Wall
Reinforced masonry (RM) has been practised in Canada for more than 50 years, mostly for construction of low- to mid-rise buildings. The National Building Code of Canada 2015 [NBCC (2015) National building code of Canada 20 National Research Council, Ottawa, ON, Canada] permits the use of ductile shear wall class for tall masonry buildings with the height limit of 60 m at sites with moderate seismic hazard and 40 m for high seismic hazard sites, but the application of ductile shear wall in tall (more than 40 m high) RM buildings is still very limited in Canada. There is a very limited research evidence related to seismic response of these structures. One of the most important properties for seismic design of ductile RM shear walls is the ultimate drift capacity, which varies significantly depending on failure mechanism(s). This paper reviews past experimental research studies on the subject and presents a database of 66 flexure-dominant RM shear walls. A statistical analysis of the data contained in the database has been performed to determine the governing parameters which are expected to influence the ultimate drift capacity of flexure-dominant RM shear walls. Moreover, this paper also proposes an approach for predicting ultimate drift capacity of RM shear walls, based on the governing parameters determined through experimental studies.
