Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.

A simply supported beam shown in figure 1, carries an uniform service (unfactored) superimposed deadload of 1.4 kips/ft. plus its own weight and a liveload of 1.5 kips/ft. The concrete strength is 3,500 psi, and the yield strength of the reinforcement is 60,000psi. The concrete is normal- weight concrete. Use the load and strength reduction factors from ACI Code.
