What do you understand by structural engineering?

Structural engineering is the branch of civil engineering which focuses on designing a structure that can withstand the stress and pressure of the environment. The main purpose of structural engineering is to build a structure safe, stable, and secure until it is in use. It is the duty of structural engineers that buildings or bridges don’t collapse. In structural engineering, engineers are trained to design man-made structures. They are taught to calculate stability, strength, and rigidity.
