Making the construction procedures of short span bridges more rational and economical, a new slab bridge system composed of steel square tubes was proposed. In the actual bridges, there are so many skewed bridges because of the site condition. So, applying the proposed bridge more widely, tests on skewed bridge were required. To clarify load transfer performance and ultimate strength of the skewed slab bridge composed of steel square tubes, loading test on the bridge structure with skew angles of 60° was conducted. Moreover, to make clear the difference between the skewed bridge and the straight bridge, FEM Analysis was also conducted. As the results of these investigations, it is confirmed that the skewed slab bridge composed of steel square tubes has sufficient strength and load transfer performance.
