A simply supported timber beam 20 cm wide and 40 cm deep carries a point load W at the middle point. The permissible stresses in flexure (bending) and shear is 100 N/cm2 and 150 N/cm2 respectively. Calculate the span length below which the shear stress will govern the safe load and above which the bending stress will govern the safe load.

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.
