PRESTRESSED WAFFLE SLAB BRIDGES -- ELASTIC BEHAVIOR

A series solution has been development to analyze the elastic behavior of post-tensioned waffle slab bridges subjected to laterally applied uniform and concentrated (patch) loads. The solution applies to bridges of rectangular and skew planforms. Realistic estimates of the orthotropic rigidities of waffle construction are used in the solution. The analysis is verified and substantiated by tests on two 1/8-scale models of prestressed concrete waffle slab bridges. The load-carring capacity of prestressed waffle-type structures versus prestressed slab-type ones is compared.
