61. In gantry girder design, what is the main purpose of a cross-section check?

1. To ensure shear resistance
2. To check for buckling resistance
3. To assess torsional strength
4. To verify axial load capacity

Answer

The correct answer is: B) To check for buckling resistance

Explanation

Cross-section checks are performed to ensure that the girder's cross-section can resist buckling under the applied loads.
