Description / Abstract:


1) For requirements pertaining to loads acting on connectors, see CSA S304.

2) For requirements pertaining to installation of masonry connectors, see CSA A371. 1.1 This Standard specifies minimum requirements for designing the following masonry connectors:

a) ties used to

i) interconnect the wythes of a masonry wall; or

ii) attach masonry veneer to its structural backing;

b) anchors used to

i) connect masonry walls to intersecting walls or to other structural members;

ii) attach stone to its structural backing; or

iii) interconnect stone;

c) fasteners used to secure a masonry tie or anchor to a structural member, or to interconnect components of a multi-component tie or anchor; and

d) repair connectors used to restore or improve masonry construction.

This Standard does not apply to

a) connectors for

i) precast concrete; and

ii) prefabricated masonry panels; and

b) fasteners used to attach equipment or fixtures to buildings.

This Standard recognizes two types of masonry connectors:

a) connectors, including repair connectors, designed in accordance with the performance requirements of this Standard; and

b) prescriptive connectors, which offer a simple prescriptive solution (or deemed-to-comply solution) to the performance requirements of this Standard when complying with the stated limiting conditions for use. 

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
