Situation #1: A reinforced concrete beam has a width of 300 mm and an overall depth of 550 mm. The beam is reinforced with five 25-mm diameter bottom bars and two 16-mm-diamter bars, both having fy = 345 MPa. Concrete strength fc' = 24 MPa. The centroid of the bars are located 65 mm from extreme concrete fibers. Unit weight of concrete = 23.5 kN/m3. The beam is simply supported over a span of 6 m and carries a superimposed deadload of 8 kN/m. Use NSCP 2010 1.1 What is the depth of compression block? 1.2 What is the stress of the compression steel? 1.3 What is the nominal capacity 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.
