is the second floor of a four-story building. a flat Consider the floor framing plan shown below. Thi The design floor live load is 90 psf. The design roof live load is 20 psf. 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...
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...
1. For the building shown below, calculate the dead load, reduced live load, and maximum design load per IBC 2012, LRFD load combinations. Beam loads should be in plf, column loads should be in kips. [To be done by hand.] Note: It is acceptable check only equations 16-1 and 16-2 of IBC 2012. a. Beam I b. Веam II olumn A/3-supporting 1 story d. Column B/2- supporting 1 story C e. Column B/2-supporting 4 stories Given loading: Dead Load 60...
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...
*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...
А w18 x 40 steel spandrel (edge) beam spans 20'. The beam supports a uniform floor live load of 1 kip/ft and a uniform floor dead load of 0.5 kip/ft. The beam also supports brick veneer weighing .6 kip/ft as a uniform dead load. The maximum allowable total load deflection for beams supporting masonry (brick or block) is L/640. Calculate the live load and total load deflections. Do the live load and total load deflections exceed the allowable deflections for...
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...
Design a W-shape floor beam for the intermediate beam marked A on the floor plan shown below. The beam is loaded uniformly by the floor with a live load of 70psf and a dead load in addition to beam self-weight of 60psf. The beam has a full lateral support provided by the floor deck. Use A992 steel (50ksi) and provisions of LRFD 壬 26 ft L-trib
1. T-Beams are used to support a floor in an industrial building. The floor is used for product storage so it must be designed for a heavy 600 psf. The floor must also support a superimposed dead load of 20 psf (in addition to the self-weight of the beams and slab. The layout of the beams and slabs is shown below. The beams span 30.0% and are spaced at 4.0” center to center. The slab is 3” thick. The concrete...
