The structure has roof G1 G4 /2 G2 GS 2o G3 FLOOR FRAMING PLAN Assume that the floor between Beams B7 and B8 is supported directly by these two beams only (not by Girders G2 and G3). Beam B7 has a self-weight of 30 plf. The...
CVE 313- 1- Design a square footing for the interior column shown in the figure. The column carries 2 k 't of uniform live load and 1.5 k/t of uniform dead load (including the self weiht of the structure), the base of the footing is 5 ft below grade, the soil weight is 100 lb/ft', and q," 5000 psf. and concrete unit weight is 150 lb/ (25 points) NOTE: Your design should only include the following (one-way shear, two-way shear,...
A three-story building has a floor layout as shown in Figure 1 with 30 ft bays in each direction. It must support a uniform dead load of 90 psf and a uniform live load of 80 psf. For LRFD design, determine the required moment and shear strength for beams and required axial strength for columns indicated below. In the calculations, assume all beams and girders are simply supported. a) The beam marked with #1 if the deck spans from line...
*please solve ALL questions Assume that the floor between Beams B7 and B8 is supported directly by these two beams only (not by Girders G2 and G3). Beam B7 has a self-weight of 30 plf. The floor slab consists of a 4-in.-thick, normal-weight, reinforced concrete slab (unit weight = 150 pcf). An additional floor dead load of 15 psf is specified to account for the weight of suspended utilities and fixtures. As an exterior beam, B7 must also support one...
6. The figure below shows the floor framing plan for an office building. The roof has the same framing plan as the floor. Select a W12 section for Column C1 in the first floor and assume the same column will be used for Column C2 in the second floor. Floor loads (applied on the 2 floor; dead load of 200 psf and live load of 300 psf Roof loads (applied on the roof: dead load of 100 psf and roof...
Assignment #1 A three-story office building, determine the total dead & live loads by columns A1 and C3 and beams. The precast exterior wall supported by the perimeter beams weighs 600 lb/ft. The floor system consists of a 6 in-thick reinforced concrete slab. 25 5-0 BEAM -0 12 14 Beam 12" Column Framing Plan
All work must be shown. You are in charge of retrofitting an existing building. The columns and girders are in place, and you have to design the beams. The building is high end (deflection limited to live load limit of L/480 and a dead load+ live load requirement of L/240). Design the most economical beam size (using conservative calculations) if the unfactored live load is 100 psf and the unfactored dead load (including beam weight) is 80 psf 30 Points...
The plan view of a typical floor of a four-story heavy storage facility is shown below. The floor and roof live load is 250 psf, and the dead load on all foors and the roof consists of the structure self-weight plus 10 psf for utilities. W 12:96 beams are spaced at 12 ft; w 18x106 reinforced one-way concrete floor/roof slab is 8" thick, each story is 12' high, and the reinforced concrete columns have a 14" x 14" cross-section girders...
