QUESTION 01. Figure 1 shows a simply supported beam and the cross-section at midspan. The beam supports a uniform service (unfactored) dead load consisting of its own weight plus 20 kN/m and a uniform service (unfactored) live load of 22 kN/n. The concrete strength is 24 MPa, and the yield strength of the reinforcement is 420 MPa. The concrete is normal-weight concrete. Use load increment and strength reduction factors from ACI Code sections 9.2 and 9.3 (i.e. 1.2 wa; 1.6w and q= 0.9). For the midspan section shown in part (b) of Fig. 1, compute oM, and show that it exceeds M,. WD = WL = 20 kN/m plus weight of beam 22 kN/m 550 600 A, =3 HD25

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.
