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 simply supported beam (L = 14-ft) is laterally braced only at the ends (see diagram). The40-kip load is a service live load. Use Fy = 50 ksi and determine whether a W12x50 is adequate. Useboth LRFD and ASD to check its adequacy. Hints: Check footnotes to verify if compact or not (no needto manually calculate). Use the AISC design-aid tables to determine Lp and Lr (i.e. don’t need tomanually determine these). Look up Cb from a table, no need to manually calculate.
A reinforced concrete cantilever beam is shown below. The beam cross section is a rectangle, 12 inches deep by 18 inches wide. Material properties are: - Concrete weight: wt = 150 pcf - Concrete compressive strength: f'c = 4000 psi - Concrete tensile strength: f't = 400 psi - Steel tensile strength: fy = 60 ksi - Stirrup consists of #4 bar - Beam is not exposed to weather or in contact with soil. Determine if the beam will crack under its own weight, if its self-weight is 250lb/ft. 10 ft -18" BEAM SECTION beam will crack beam will not crack unknown, not enough information to calculate

An A36 W14X605 simply supported steel beam with span “L” carries a concentrated service liveload “PLL” at midspan. The beam is laterally supported at supports and its midspan. Consider its beam selfweight to be its service deadload, “w” (use ASEP steel manual for selfweight, w and other section properties). In checking section's compactness, calculate the upper limit for non-compact web category? Express your answer in 2 decimal places.
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?

Question 4: Select an appropriate W310 section of ASTM A992 steel (F, = 345 MPa) as the beam-column in an unbraced frame subjected to the factored loads, including biaxial bending moments, as shown in Fig. 4. The beam-column is laterally braced at the two ends only. (Hint: I would start with W310x118 and then decide if this is an appropriate choice or a heavier/lighter section is necessary depending on the outcome of checking interaction equations.) 1040 kN 1040 kN 125 kNm 85 kNm W310 W310 7000 %3D II 235 kNm 50 kNm 1040 kN 1040 kN Figure 4
