Problem 5: A beam is 250 mm in width, 500 mm in total height and 3.5 meters in length. This beam was tested under 4-points loading, and the shear span (a) was 1.2 meters (this is the distance between the applied load and the support). Tests on the same concrete used in this beam were conducted on cylinders and the compressive strength was measured to be 32 MPa. a- Calculate the flexural Modulus of Rupture () as recommended by ACI code b- Calculate the bending (i.e. flexural) moment at which flexural cracking is expected c- Calculate the maximum total load which can be carried by 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.
