CHAPTER 2
Load Combinations
2.1. Determine the strength design load combinations for a reinforced concrete beam on a
typical floor of a multistory residential building using the nominal bending moments in
Table 2.11. All bending moments are in foot-kips. Assume the live load on the floor is less
than 100 psf.
