Practice

Interior floor girders, spaced 12 ft on center, span 36 ft and carry a one-way slab; each girder supports a single floor. The floor dead load (slab, framing, and superimposed) is 90 psf and the unreduced live load is 50 psf. Live-load reduction per ASCE 7 is permitted, with $K_{LL}=2$. Using the LRFD combination $1.2D+1.6L$, the factored uniform load on one girder is most nearly:
