Strengthening of Existing Inverted-T Bent Cap Ledges

Inverted-tee bent caps are used extensively throughout Texas to economically satisfy geometric constraints and appearance. Over the decades, the design approach has changed in response to research prompted by observed cracking. With a change in design philosophy, many of the early inverted-tee ledges are deficient when evaluated against the current design approach. One example is the substructure supporting the lH-35 upper deck through downtown Austin. The research team will develop solutions that provide increased capacity of existing substructure components on numerous direct connectors and other bridges including the highly congested lH-35 upper deck through downtown Austin.
