What is it about?

It is important to study the effect of strengthen openings on concrete beams thresholds in order to predict future effects.

Why is it important?

Openings in concrete beams cause a sudden change in section, which creates a shear stress concentrated at the edges. Therefore, the openings must be strengthen.
