Question

The floor plan of a building in the preliminary stages of design is shown below. The floor supports a 140 ps uniform load. The connections between all members are simple shear connections (shear tabs).

 

find the reactions and maximum shear and bending moment. However, you should be able to find these values using equations of equilibrium and shear and bending moment diagrams.

  1. Draw the FBD of beam B2 based on tributary load analysis for the given loading and floor span direction. Show the applied load and find the reactions
  2. Report the maximum shear (kip) in beam B2.
  3. Report the maximum bending moment (kip-ft) in beam B2.
    Answer: Mmaz=126 kip-ft
  4. Draw the FBD of girder G2. Show the applied loads and find the reactions of G2.
    Note that six beams like B2 are connected to G2 one on each side of the girder at the three connection points shown in the figure.
  5. Report the maximum shear (kip) in girder G2.
  6. Report the maximum bending moment (kip-ft) in girder G2.
    Answer: Mmar=504 kip-f
