Example Assuming that the governing “a” is due to the overall building width impacts the purlin design greatly. Earthquake actions in Australia.

Lysaght and Strammit give max span lengths for given idealized loadings and span configurations, I find the capacity’s are generally driven by moment capacity and deflection criteria. So for all those steps the local pressures should be applied in the vicinity of the steps. I believe some engineering judgement is required, to get a good insight into how the wind loading would be working I would try to draw some stream lines across the building.
If you know the section properties than you can calculate it’s capacity. Close this window and log in. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Also Appendix D, Paragraph D1.

The terrain category can be broken down into 5 groups and refers to the terrain located in the direction of the approach winds flowing towards the structure. Tue 13 Mar – If I’m wind hitting a corner eave on say a smaller, isolated portion of roof, I don’t care how big the roofs are on different levels??

Does anyone else have any thoughts on the questions I had above?? Defense manufacturing is all about project manufacturing and project accounting. Snow and ice actions. But it should also be from windward edges. Would be good if the code gave a bit more insight into these things Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
The actual purlin design is no different to the design of any other steel member.
Not just the basic pressure x purlin spacing! Previous Australian editions AS Holmes, I have attached the relevant page. Or maybe I shouldn’t be mixing the local factor from Appendix D with the one in Section So far, the Universe is winning.

Patch loadings etc etc. The “a” should be based on the whole building. In particular when you have the situation where you have one large building ‘footprint’ with smaller roofs at different heights.
