Hiii STAAD experts =')
actually I've started modeling my structure, which will carry a photovoltaics (PV's),
since it's my first time to do the full analysis and design, I still have many questions:
1. My structure is going to carry about 400 kg, which is the PV's weight, and going to resist a wind load with speed of 150 km/hr, the PV's will lay down on the purlins which have a length of 16.8m, which it's material is an Aluminum (the locally formed lipped channel section 40mm width, 60mm height, lip length 20mm and thickness of 4mm), I've tried to use the Section wizard to get a section looks like it, but it didn't work with me, I couldn't get it ='( , what can I do in this situation?????
2. how to analyse the dead load on purlins and rafters????
I really need your help as soon as possible, thanks a lot in advance =')
