An RC beam of 350mm wide and 500mm deep is 3m long over a cantilevered span. The only dead load that it would carry is its own weight. Using d=430mm, f'c=34.5MPA, and fy=414MPA, determine the following: a. The tensile reinforcement if it will carry a uniform live load of 5kN/m. (mm²) b. The tensile reinforcement if it will carry a uniform live load of 14.5kN/m. (mm²) c. The tensile reinforcement if the beam is desired to be in balanced condition. (mm?) Hint: The values of minimum and balanced tensile reinforcements can be solved using only the ACI

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.
