[[Structural engineering]] depends upon a detailed knowledge of [[Structural load|loads]], [[physics]] and [[Building material|material]]s to understand and predict how structures support and resist self-weight and imposed loads. To apply the knowledge successfully structural engineers will need a detailed knowledge of [[mathematics]] and of relevant empirical and theoretical [[design codes]]. They will also need to know about the [[corrosion]] resistance of the materials and structures, especially when those structures are exposed to the external environment.

The criteria which govern the design of a structure are either serviceability (criteria which define whether the structure is able to adequately fulfill its function) or strength (criteria which define whether a structure is able to safely support and resist its design loads). A structural engineer designs a structure to have sufficient [[Strength of materials|strength]] and [[stiffness]] to meet these criteria.
