4. A two story office building has interior columns spaced 25 ft apart in two perpendicular directions. The columns are fixed at the roof, the second floor and the ground floor in both directions. Consider the dead load (4 inch-thick reinforced concrete slab at the roof and 6 inch thick reinforced concrete slab at the floor) as well as appropriate live load. Ignore other dead weight other than shown. Determine the following using A992 steel: (20 points) 1) Dead load...

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...

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...

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...

A six-storey office building consists of a basement, ground floor (1t floor), five upper floor levels (levels 2 through 6), and a roof. The typical layout of the floor system is shown below, in which each floor girder spans 6 m and floor joists span 4 m. The total plan area of the building is therefore 12 m x 8 m. The roofsystem is similar to the floor system. All of the floors support a uniformly distributed dead load of...
