A rectangular concrete beam has a width of 300mm and an effective depth of 450 mm to centroid of the tension bars. The beam is reinforced with six-32 mm ᴓ tension bars placed in two layers with the outer layer having a depth of 478 mm, and two 28 mm ᴓ compression bars with centroid 65 mm from the extreme tension fiber. Use the 2010 NSCP, fc’ = 34.5 MPa and fy = 345 MPa. Assume the concrete displaced by the compression steel cannot be neglected and that compression steel yields. Determine the following: The balanced steel ratio if the beam is singly reinforced. The maximum steel ratio for a singly-reinforced section in tension control. The maximum steel area in mm2 for a doubly reinforced section in tension control.

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.
