A doubly reinforced rectangular concrete beam has a width of 300 mm and an effective depth of 500 mm. The beam is reinforced with 2200 mm? of steel in tension and 628 mm? of steel in compression. The effective cover for compressive steel is 50 mm. Assume that both tensioned and compressive steel yield. The grades of concrete and steel used are M-20 and Fe-250 respectively. The stress block parameters (rounded off to first two decimal places) for concrete shall be as per IS: 456-2000.The depth of neutral axis is

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.
