Abstract:
Strut-and-tie models make the design of portions of complex structures transparent. This example, a pier table from a cable stayed bridge, is developed to show how strut-and-tie modeling can be used for an area that may be exposed to cyclic loading and how the results from alternate loads may be superimposed upon one another. The pier table transmits forces from the pylon, through an integral superstructure connection, to individual support legs. The pier table also creates an area for the transmission of superstructure forces. This example briefly describes the model development based upon the perceived flow of forces within the structure. The tie reinforcement is then detailed and the nodal zones checked.
