Concept explainers

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.

A 35-feet simply-supported floor beam, made of ASTM A572 Gr. 50 (Fy = 50 ksi) W18x50 hot-rolled section bent about its major axis, is to carry a superimposed uniform dead load of 0.45 kip/ft and uniform live load of 0.75 kip/ft throughout its entire span. The beam is braced against lateral deflection at its supports and at its midspan. Assess the adequacy of the beam to carry the given loads. Use IBC limits for satisfying deflection requirements. Use LRFD specifications.
The service load bending moments on a beam are 128 kip-ft for dead load and 107 kip-ft for live load. The beam is 12 in. wide, f'c is 3000 psi and fy is 60 ksi. Determine Mu. Mt. p. R. the depth of the beam and the As of tensile reinforcing required. How many no. 8 bars or No. 10 bars would have the required As?
