Overview
This tutorial guides you through modeling and designing a 70 m two-span PSC composite I-girder bridge with a multi-column pier in MIDAS CIVIL NX. You will define time-dependent materials and NU1600 girder sections, configure tendon profiles and construction stages, and model tapered pier caps, RC columns, and reinforcement. You will then apply Canadian moving loads, generate load combinations, and examine reactions, deformations, member forces, critical vehicle positions, and tendon losses. Finally, you will perform PSC girder and RC pier design checks in accordance with CSA S6-19. By completing this quest, you will learn how to: - Generate a two-span PSC bridge and its substructure using the bridge wizard - Define time-dependent materials, composite sections, and tendon profiles - Configure prestressing loads and construction stages - Model tapered pier caps and multi-column RC piers - Apply Canadian moving loads and generate design combinations - Evaluate structural responses and tendon losses - Complete PSC girder and RC pier design checks to CSA S6-19
