	Structural Design - Methods (986 words) The goal of structural design is to determine the number, material composition and thickness of the different layers within a pavement structure required to accommodate a given loading regime. Structural design is mainly concerned with determining appropriate layer thickness and composition. In pavement design, the phenomena are the stresses, strains and deflections within a pavement structure, and the physical causes are the loads and material properties of the pavement structure. Structural engineering - Wikipedia, the free encyclopedia (553 words) Structural engineering is the field of civil engineering particularly concerned with the design of load-bearing structures. Structural engineers need to design structures so that while serving their useful function, they do not reach collapse (structural failure or ultimate limit), and do not bend, twist, sag or vibrate in undesirable ways (serviceability limit). The sum of the forces acting on the structure are equal to the sum of the supporting reactions - the forces acting on the structure are in equilibrium.
