oa Civil Engineering = Siviele Ingenieurswese - The lateral load carrying capacity of wall ties used in cavity wall construction in the Western Cape

Volume 20, Issue 2
  • ISSN : 1021-2000



The aim of the testing was to compare the relative positives and negatives of the Butterfly Tie and the Crimped Tie with regard to water transfer, and tensile and compression strengths based on the Australian Code (AS 2699-1984) requirements, as these are more comprehensive. The motivation was because the Butterfly Tie has been promoted in cavity wall construction in South Africa for the following reasons: (i) the NHBRC (National Home Builders Registration Council) compels contractors to use the Butterfly Tie; and (ii) SABS 28:1986 and SABS 0164-1:1980 also compel the use of the Butterfly Tie, even though there is an anomalous statement in the specifications.
