I am designing steel roof members for a church. The roof is full of gables and also some flat areas. The gables are framed with light gauge steel trusses while the flat areas are framed with precast plank. In certain areas, the trusses and the plank are both supported by a single steel beam. My maximum span is around 30' and the ceiling structure is suspended acoustical tiles.
I am curious to see what people would use for deflection limits based on IBC. Are there reasons to put an absolute limit on deflection of a beam supporting plank?
