The present study investigates computer-automated design and structural optimization of concrete slab frame bridges based on a complete 3D model. For this regard, a code with several modules has been developed to produce parametric models of slab frame bridges. Design loads and load combinations can be chosen either based on the Swedish design standard for bridges or the Euro-code. The necessary reinforcement diagrams to satisfy the ultimate and serviceability limit states including fatigue checks for the whole bridge are calculated according to the aforementioned standards. Optimization techniques based on the genetic algorithm and the pattern search method are applied. The presented results highlight the efficiency of the applied optimization algorithms. This methodology can be applied in the design process for a time-effective, material-efficient and optimal design of concrete slab frame bridges.
