Overview
In this quest, you will model, analyze, and design a two-span steel composite I-girder bridge in MIDAS CIVIL NX. Using the Steel Composite Bridge Wizard, you will define four steel girders, the concrete deck, cross-bracing system, bearings, reinforcement, and composite section properties. You will also configure the construction sequence and time-dependent concrete behavior based on the New Zealand Bridge Manual requirements. You will apply static loads and New Zealand HN moving loads, calculate dynamic load factors for each span, and define a response spectrum based on NZS 1170.5:2004. Construction stage, moving load, eigenvalue, and response spectrum analyses will then be performed. After the analysis, you will evaluate reactions, shear forces, bending moments, critical vehicle positions, concurrent forces, and vibration mode shapes. Finally, you will generate load combinations and verify the composite girders according to AS/NZS 5100.6:2017, including reinforcement and shear connector requirements. By completing this quest, you will be able to: Generate a steel composite bridge model using the Wizard. - Define composite sections, bracing, bearings, and reinforcement. - Apply New Zealand HN moving loads and dynamic load factors. - Perform construction stage and response spectrum analyses. - Verify steel composite girders and generate a design report.
