H.W.5: For the simply supported beam shown below reinforced by 4025 bars (f₁ = 420 MPa), the concrete strength (f= 21 MPa) evaluate the following: 1- Check the actual flexural stresses in concrete and steel if the span length equal to (4 m), dead load 8 kN/m including self-weight of the beam, live load equal to 10 kN/m. 2- The length of beam span that makes the concrete in tension face starts to crack. 3- The actual stress in concrete and steel if the span length of the beam is equal to 7 m. WI= 10 kN/m

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.
