COASTAL CONSTRUCTION MANUAL
Illustration A. Force diagram for diagonal bracing
Solution for #1: The tension force in the diagonal brace can be found as follows:
Rod bracing is used and assumed to act in tension only because of the rigidity of the rod brace in tension and
lack of stiffness of the rod in compression.
• The tension brace force is calculated as follows:
Interaction of the soil and the pile should be checked to ensure that the uplift component of the brace force
can be resisted.
