SHEAR PUNCHING OF BRIDGE DECKS
The report summarizes the findings of the research on the susceptibility of reinforced concrete slabs of beam-slab type highway bridges to shear punch failure due to the wheel loads. The investigation included a review of literature on shear punching of bridge decks due to patch loads, and five parametric investigations covering a wide range of slab and wheel loading configurations. The patch loads considered correspond to the wheel loadings of trucks and dollies of special vehicles. It has been conclusively found that the bridge decks will not undergo shear punch failure due to the single or tandem wheels of overloaded vehicles. The mode of failure of the deck slab is essentially due to the flexural behavior.
