1. drawing show wind pressure designed for is 395pa, how about area that has higher pressure?
2. any reason there has to be end bracing and intermediate bracing? How much safety factor is provided?
3. without bracing, how much is the safety factor? Is the bracing only designed for wind load?
4. the parallel intermediate bracing does not provide proper stability, should it be crossed? if only needed.
5. pre-embedded holes will incur conflict with diaphragm holes at abutment, need to be carefully laid out.
6. how the tension force is 0.5 of compression force? I check the compression member calcs, and it matches KL/r = 80. if thinner member is used, this is unsafe.
7. the intermediate bracing is an addition to the existing standard drawing, any particular needs to add the intermediate bracing?
