Thanks Istructeuk for the document, really helpful!![bigsmile] Motorcity, my issue is that the seismic loads acting the steel deck exceed the connectors capacity of the deck, even with a spacing of 6 inches between the connectors. Then I will need to add horizontal x-braced to withstand the...

We are designing a large commercial warehouse. The distance from the exteriors vertical bracing are large (around 300 ft.) We have a large axial load in the roof steel deck diaphragm, the loads exceed the resistance of the connectors of the deck. We decide to use steel angle (2L) sections as...

I'm designing a concrete reclaim tunnel with 1.5meter thick walls and slab. I'm looking for a reference book or paper for any precautions to take care. Anyone have any can send me one, thanks
