Structural engineering is a branch of civil engineering, and its applications are diverse. A great deal of what structural engineers do involves designing structures such as buildings, bridges, tunnels, etc. It’s the structural engineer’s responsibility to calculate different forces (such as hurricane, wind and earthquake forces), design the structure to fit a pre-determined layout, and decide on what structural systems to use. The structural systems include steel, concrete, masonry, wood and other materials from which the engineer selects beams, columns, and other members that make up the building support. Structural engineers are involved in the design of new buildings, renovations and repairs and also handle the demolition of buildings. Additionally, structural engineers inspect structures before and after construction to determine if there are any structural concerns and ensure proper construction.
