1/ - Column shear analysis

- Dynamic structural analysis

- Blasting pressure analysis

- Wind load analysis

2/ Flexural failure

- Tension failure

- Compression failure

3/ Shear failure : to be resisted by increasing the cross section or adding more stirrup. The second choice may  be easier in practice, however not so economic. Ductile materials can sustain more load in the tension test prior to their failure. To verified whether flexural failure or shear failure occurs first, ration between nominal moment and nominal shear is to be checked.

Tension crack in comp. modeling appears to be perpendicular to the plane section of the beam. Shear crack on the other hand tens to incline at an angle of around 45 deg.
