Design of Concrete beam A rectangular beam has a width of 375mm and has an effective depth of 450 mm. f'c = 25 MPa, Fy = 300 MPa. 1. Determine the moment capacity if it is reinforced with steel area in tension w/ 12-25mmø reinforcement bar. Use 0.9 as moment reduction factor. 2. Determine the depth of stress block if steel in compression As' = 3000 mm² is added with steel covering of 50 mm below the top of the beam. 3. Determine the moment capacity of the beam reinforced for tension and compression. 375 0.85/c' 0.003 450 12-25mm0 bar N.A 265.74 (d-an) T= As Sy Es 184.26

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.
