78Approximate Analysis of Continuous Beams and One Way Slabs

Under typical conditions, for continuous beams and one-way slabs with more than two spans the approximate moment and shear values given in Figure 7.2 may be used in lieu of more accurate analysis methods. These values are from ACI 8.3.3.
