SKEWED MULTI-BEAM BRIDGES WITH PRECAST BOX GIRDERS

The research completed under this project demonstrates the reduction in required design moment that can be achieved by consideration of the skew angle and aspect ratio of a multi-beam bridge. It is primarily directed toward precast multi-beam box bridges of the type currently built in Texas. Other similar multi-beam or solid slab structures with simple spans can also be handled. A data generator computer input assist was written which provides the data for a previously developed program so that accurate solutions can be obtained with a minimum of input. A field load test was performed on a full-scale skewed bridge. Comparison of the measured values with those predicted by the analysis methods was good. /Author/
