| 摘要： | The present study is aimed towards the development of an improved methodology of bridge design for barge impact. Analysis procedures developed in the present study can be integrated into the current vessel impact design foundation given by the AASHTO Guide Specification for Vessel Impact Design of Highway Bridges. The objectives of the present study are: (1) Development of a statistical method by which barge traffic data can be used for impact design of inland waterway bridges. (2) Derivation of multiple-barge impact time-histories using the single barge load-deformation curve provided in the AASHTO Guide Specification. (3) Derivation of design impact response curves (4) Development of barge impact analysis procedures that may be used in place of the current AASHTO Equivalent Static analysis procedure. A design example is also included in Section 5 to illustrate the use of the pseudo-dynamic analysis procedure. The results of this study makes possible true analysis and design of bridges susceptible to barge traffic. True dynamic analysis includes member loads that result from the inertial effect of the loading. This is in contrast to the current AASHTO equivalent static method which neglects the dynamic effects of the impact loading. |
