Problem 1 Floor Systems Self Weight, Tributary Load and Load Path (25 pts.) The attached structure supports a floor system which will be used for office space. This structure is located inside a larger structure and it is independently supported both laterally and vertically Essentially, it stands by itself. It is call a mezzanine system. Lateral bracing on all four walls is not shown for clarity. The sections provided below are preliminary. Using the information provided on the sketch determine the following loads . Is the system one or two way action? 2. Interior joist 2 A-B uniformly distributed w_dead- 3. Edge joist 3 A-B uniformly distributed w dead 4, Interior girder 2-3 B uniformly distributed w-dead- 5.

    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...

    *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...
