Reinforce Concrete: A rectangular isolated beam has a clear span of 8.0m and carries a service live load of 60KN/m and 15KN/m including its own weight. The beam has a width of 350mm and an effective depth of 700mm. It is reinforced with 6 – 28mm rebars in two rows. Total depth of the beam is 800mm with F’c = 27.6MPa, Fy = 414MPa, Fyt = 280MPa. Use sand lightweight concrete having a unit weight of 2400Kg/m3. a. Using Detailed calculation method for shear strength for concrete, determine the shear force to be resisted by the shear reinforcement at the critical section from the face of support. b. Determine the spacing of 10mm shear reinforcement required by the beam due to its load. c. Determine the point where no shear reinforcement are needed measured from the center of the beam

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.
