A structural engineer designs a structure such as building, bridges, tower etc. to withstand
forces. Forces come from many sources such as the weight of the building, the people inside
the building, earthquake, wind or any other environmental loads. When designing a
structure the engineer must account for its safety, aesthetics and serviceability while taking
in to consideration economic and environmental constraints. The design process is both
creative and technical and requires fundamental knowledge of material properties and laws
of mechanics that govern material response.
