| 摘要： | High Performance Steel has been used in hundreds of bridges across the United States. A large percentage of these bridges have used the HPS in the form of hybrid girder designs. One limit with hybrid girder design, which decreases the beneficial aspects, is that tension field action is not allowed when determining the shear capacity. The objective of this research is to validate the tension field action behavior in hybrid plate girders. The goal is to allow TFA in hybrid girders resulting in more economical design of steel bridges. This report includes a thorough presentation of tension field action and moment-shear interaction in plate girders, and in particular hybrid plate girders. It presents a comprehensive presentation on experimental test girders with a detailed analysis and examination of test behaviors. As a result of this work, in addition to work of others cited, tension field action for hybrid girders has been adopted by AASHTO for bridges and removal of the moment-shear interaction has been adopted by AASHTO for bridges and AISC for buildings. |
