Structural steel buildings frequently are designed with diagonal bracing systems to resist lateral loads (horizontal forces resulting from wind or earthquake loadings). A certain bracing system is subjected to the following loads: dead load, 13.3 kips, occupancy live load -6.9 kips, roof live load – 1.3 kips, snow load – 1.3 kips, wind load – 150.6 kips, and earthquake load – 161.1 kips. a. Determine the required factored load capacity for LRFD. Which load combi- nation controls? b. Determine the...

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...

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...

A column in a 2-story building supports loads from the second floor and the roof. Loads were calculated and are provided below: Roof Dead = 18,000 pounds Roof Live = 14,400 pounds Wind (down) = 36,000 pounds Wind (up) = 60,000 pounds Floor Dead - 32,000 pounds Floor Live - 39,000 pounds. Using applicable ASD load combinations (refer to Ch. 2 of your textbook), determine the following: a. The maximum axial compression load in pounds for the column supporting the...

1) [Design] A reinforced concrete column is to be sized to carry pure axial compressive load. According to ACI 318, what is the smallest possible cross-sectional area (Ag) that the column can use in design supporting an axial dead load of 200 kips (unfactored) and live load of 400 kips (unfactored). Use fc = 4,000 psi and fy = 60 ksi. Assume pe = 0.08 and ties for transverse reinforcement. Be sure to include the appropriate design factors and use...

roof A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 45 ft-kips, and the maximum moment for the service live load is 63 ft-kips (these moments occur at the same location on the beam and can therefore be combined). 2-3 a. If load and resistance factor desig n is used, determine the maximum...
