Use Figure and select an open-web steel joist for the following floor system. The span length is 22 feet and the joist spacing is 4 feet. The loads consist of a 40 psf live load, a partition load of 20 psf, a slab and metal deck system weighing 32 psf, and a ceiling and light fixture weight of 5 psf. Assume that the slab provides continuous lateral support. Is there likely to be a deflection problem? Why or why not?
