A flitch beam is composed of two 50x300mm planks reinforced with a 12.5mm steel plate as shown. Assume that continuous lateral support is furnished by a floor system supported by the beam. Use A36 steel with an allowable bending stress of 150 MPa, Fy = 250 MPa. Es = 200,00MPa, Ew = 7692MPa, fw = 4.3 MPa. The beam is on a simple span of 4.8m and supports a uniformly distributed load of 7.3 kN/m which includes the weight of the beam. Allowable stresses for shear: Steel: fv = 0.60Fy MPa Wood: fv = 0.58 MPa Determine the following: a.) The resisting moment of the flitch beam b.) The applied moment to the flitch beam c.) The shear capacity of the flitch 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.
