TechNote#017 Canopies: Flat Roof Carports, Verandahs, Pergolas and Patios

Various structural forms (SF) of canopies, typically constructed for use as carports, verandahs, pergolas and patios. {NB: Pergola and patio have otherwise been redefined by marketing: thus lost traditional meaning in terms of sales, but not in terms of regulations and codes.} If a carport, or verandah is made from cold-formed c-section and it matches […]

Daily Challenge Day 3

I was thinking about writing on the approximations and simplifications employed in the timber framing code and the hassles it creates when dealing with situations beyond the scope of the timber framing code (AS1684). If not aware of the simplifications and carry out calculations to the timber structures code (AS1720) then have a good chance […]

THE GUIDE Not having a qualitative understanding of the […]

TechNote#001 INITIAL INVESTIGATION INTO THE IMPACT OF THE ENERGY EFFICIENCY REQUIREMENTS OF BUILDING CODES ON GLAZED ENCLOSURES

{Originally wrote as technical note around 2005} INTRODUCTION The following technical note indicates some of the constraints on design that need to be considered when modifying an existing dwelling, by increasing internal floor area by enclosing a roofed area with glazing. (eg. A verandah or porch). Such extensions are generally not intended to increase habitable […]

Example Canopy Design and Documentation: Carports, Verandahs and Pergolas

Typically our involvement with carports, verandahs and pergolas, or more generally canopies, is the supply of structural reports or certification. Both reports and certification involve structural calculations, the difference between the report and certification is that we don’t compile the calculations into a report. Certification is only really appropriate for simple common place structural forms. […]

Canopy Design: pt#1 (Basic Procedure)

Free standing canopy (carports etc..) design is similar to the requirements for shed design. The primary difference is that with no wall cladding the wind load pushing against the side of the canopy is less. There is still a side ways load on the canopy, it comes from the horizontal component of the loads on […]
