RIGID FRAME REINFORCED CONCRETE SKEWED SLAB BRIDGES

The design of skew slab bridges is complicated by higher shears and moments to develop near the obtuse angle. While the finite element method can be used to compute these moments and shears, it is time consuming for everyday design. A linear elastic finite element analysis was used to investigate the effect of dead loads, AASHTO live loads and earth pressures on 20 different bridges with spans ranging for 15 ft to 60 ft and skew angles varying from 0 to 60 degrees. The results of the study were used to produce design charts which account for the effects of skew.
