Offshore steel trestles (OSTs) are commonly used to construct sea-crossing bridges. Presuming OSTs to be elastic to hydrodynamic hazards during their service lifetime is economically unacceptable due to their use as a temporary facility. In order to enhance operational safety and also reduce building costs, a nonlinear analysis framework is developed based on pushover approach and is applied to assess the nonlinear response of OSTs subjected to wave and current loads. The framework yields a nonlinear response curve that supplies structural nonlinear behaviors, capacities and plasticity development as functions of wave height. The dynamic amplification, current speed, loading direction, marine growth and soil-structure interaction (SSI) on the nonlinear response of the example OST under wave and current loads are then investigated. The results show that the structurally vulnerable positions of OST are located at the bottom of the piles and the joints connecting the brace to the pile.
