A rectangular concrete beam having a width of 250 mm and an effective depth of 350 mm will be design loads as stated. The steel yield strength fy = 275 MPa and concrete strength f’c = 20.7 MPa. If the compression steel is found necessary, it will be placed 60mm from the extreme compression fiber of the beam. Neglect the effect of the displaced concrete and use NSCP 2010. A.Determine the number of pieces of 20mmØtension steel for a singly reinforced section reinforced with maximum steel for tension control. B.Determine the number of pieces of 20mmØtension reinforcements if beam is to carry a factored design moment of 80 kN.m. C.Determine the number of pieces of 20mmØtension reinforcements if beam is to carry a factored design moment of 135 kN.m. D.Determine the number of pieces of 20mmØcompression reinforcements if beam is to carry a factored design moment of 135 kN.m. hello please answer this thanks

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.
