Abstract:
This example demonstrates strut-and-tie principles to design an internal diaphragm for a segmental concrete girder bridge. The diaphragm carries vertical shear and torsion from the webs of the box girder around the access opening to the bearings on the pier cap. Tie forces are determined, and reinforcing steel is selected. Stress checks for the struts and nodal zone are provided.
