Structural loads or actions are forces, deformations, or accelerations applied to a structure or its components. Assessments of their effects is carried out by the methods of structural analysis. Excess load or overloading may cause structural failure, and such possibility should be either considered in the design or strictly controlled.
Engineers often evaluate structural loads based upon published regulations, contracts, or specifications. Accepted technical standards are used for acceptance testing and inspection.
With clear, concise language, Seismic Loads: Guide to the Seismic Load Provisions of ASCE 7-05 illustrates key concepts and guides structural engineers in applying the most current thinking in this rapidly changing discipline to the design of new structures. The Standard includes provisions for seismic design of structures, as well as the provisions for determining live, flood, wind, snow, and atmospheric ice loads.
