| 摘要： | Inverted-T bent caps are used extensively throughout Texas to economically satisfy geometric constraints and to provide an aesthetically pleasing appearance. With a change in design philosophy, many of the early inverted-T bent caps are deficient when evaluated against the current design approach and future increased traffic demands. When replacement of deficient bent caps is not practical due to cost, interruption to traffic, and/or the acceptable condition of other parts of the structure, robust proven techniques for providing supplemental strength are needed. Because no formal guidance is available in current standards, there is a need to investigate the effectiveness of strengthening solutions that adequately address deficiencies and reduce observed in-service damage of existing inverted-T bent caps. |
