As this is our first edition, we thought that it was timely to introduce you to the man behind our company.
As part of e-struct’s continuing professional development, we took the opportunity to attend a presentation organised by Engineers Australia that ran August 5th, at Punthill Apartments Dandenong. John Wilson, Dean of Science, Engineering and Technology at Swinburne University of Technology discussed the effects of seismic actions on concrete structures.

A new Australian Standard came into effect for Masonry structures in 2010. This code (AS4773 Masonry in small buildings –2010) was brought about to cover predominately small residential structures.
An example of a typical garage wall application would be a 2700 height garage wall within a new estate (Wind Class N2) using 110 wide brickwork. Table 9.2 requires standard 230SQ engaged piers have a spacing of 960mm max. This is a marked difference from BCA 2011, Volume 2, Section 3.3.1 which allowed 230SQ engaged piers at 3000mm spacings max.
