ABSTRACT
Traditionally, masonry design in Canada has been carried ollt using the Working Stress Design (WSD) method and utilizing procedures that were developed in part through theoretical and experimental studies and also through traditional practice and experience. More consistent levels of safety and economic efficiency can be achieved by incorporating the Limit States Design (LSD) approach in the design of masonry structures just as in the design of steel and concrete structures. The 1995 publication of CSA Standard S304. l-94, Masonry Design for Buildings (LSD), is providing designers with a LSD procedure for masonry design. Consequently, the LSD approach also had to be extended to cover the design of masonry connectors. The publication of the 1994 CSA Standard AJ 70, Connectors jor ,\lasomJ’. provides designers with LSD procedures for the design of connectors for masonry. This paper deals with the factored resistance of masonry connectors and the background behind selecting different values for the resistance reduction factor ยข.
