STRUCTURAL MODELING FOR AUTOSTRESS DESIGN BY LOADING THROUGH A PRECAST DECK

Research efforts are described that aimed at developing design methods that will permit designers to apply the autostress concept to plate girder bridges, and to incorporate these concepts into the American Association of State Highway and Transportation Officials (AASHTO) bridge specifications. The autostress research is aimed at maintaining simplicity of completed steel structures to minimize total cost including fabrication. The main thrust of the modular concrete deck portion of the research involves the extended use of higher strength concretes and modular deck panels. The primary emphases of the deck research are listed. An additional thrust of the research is the study of the distribution of live loading to the individual girders. Details are given of the design approach, model bridge design, fabrication and erection, and instrumentation. The model bridge test plan is summarized. Results collected to date indicate that the behavior of the bridge agrees with elastic theory.
