PROBLEMS IN DESIGNING PRESTRESSED SEGMENTAL CONCRETE BRIDGES

Prestressed segmental concrete bridge construction offers unique advantages over conventional methods of bridge construction. As a result, this relatively new method has gained wide popularity in the construction industry. However, as with any innovative technique, there are some design problems associated with these bridges that require attention. Experience has indicated that damage may occur at local details in these bridges. Some design problems that can be solved with the use of advanced analysis methods to obtain a better understanding of bridge behavior are discussed. The finite-element method, in conjunction with representative material models, is ideally suited for providing a better understanding of the structural behavior and for obtaining accurate response predictions. Two representative examples are analyzed and discussed to demonstrate how to use these procedures in the design process. Response predictions obtained from the application of these advanced analysis methods to segmental concrete bridges can be used as a basis for improving designs. Further examples are given, and finally the importance and implementation of such methods in routing design are briefly discussed. (Author)
