A Look to the Past: Reevaluation of the Performance of Tall Slender Concrete Masonry Walls

Source

Slender masonry walls (SMWs) with a slenderness ratio (kh/t) over 30 have stringent design requirements in North American codes (TMS 402/602-16; CSA S304-14). As a result, in some design scenarios masonry struggles to be a competitive option compared to other systems. The limits and requirements for tall walls are largely based on a comprehensive investigation conducted by the American Concrete Institute and the Structural Engineers Association of Southern California 41 years ago. Since then, understanding of these slender elements has advanced, and the tools for a more refined analysis have become easily available to practicing engineers. Furthermore, recent studies highlight the need to reevaluate the performance of these walls and the requirements in the design standards. In this study, a full-scale SMW built using concrete masonry units subjected to eccentric axial and cyclic out-of-plane loads was tested, the first of a series of tests conducted at the University of Alberta to reevaluate the strength and behavior of tall concrete masonry walls; the test aimed to generate a rational design procedure for modern SMWs.
