摘要: |
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed deck panels. The bridge was designed according to the alternate load factor design (ALFD), or autostress, procedures. The project was jointly sponsored by the Federal Highway Administration (FHWA) and the American Iron and Steel Institute (AISI). Initiated in late 1982, the model bridge project was part of a comprehensive research program conducted by AISI to extend inelastic design procedures to continuous girders with noncompact elements. The American Association of State Highway and Transportation Officials (AASHTO) guide specification for ALFD procedures permitted the use of inelastic design methods only for bridges made of braced compact sections. In the model bridge test program, elastic lateral live-load distribution was studied at the service load level. At the overload and maximum load levels, the adequacy of the ALFD limit-state criteria to satisfy related structural performance requirements was analyzed. The behavior of the concrete slab made of precast deck panels was studied at all three load levels. |
