Body: "Structural engineering" is the field of the applied physical laws and empirical knowledge of the structural performance of different materials and geometries.
R.C. Hibbeler, Alan Blank, Nigel Hewson are some authorities of "Structural engineering".
Some reasons we look at "Structural engineering" include better understand the architecture, mathematics, and physics of building design and construction.
Some subfields in "Structural engineering" include history, structural failure, structural elements, materials.
