Analytical and Experimental Evaluation of Stiffness Parameters of Voided Concrete Slab Bridges. Volume 1. Three Dimensional Finite Element Analysis of Posttensioned Voided Slab Bridges

摘要

The study investigates the finite element computer aided structural model development and analysis for longitudinally and transversely posttensioned, voided concrete slab bridges. Straight and curved, two span, continuous models are developed and analyzed. Comparison of the results of the two span straight continuous computer model to some experimental results from Canada is illustrated. The comparison was used to determine the viability of the computer modeling procedure. A prototype curved slab is also modeled and analyzed.
