Unformatted text preview: (Summer 2003) – CVEN 444 CVEN 444: STRUCTURAL CONCRETE DESIGN CLASS PROJECT The structural floor plan of a three-story (ground floor, two suspended floors, and a roof) office building is shown on the next page. The roof covers the hole used for the elevator shaft and stairwells. The new building will be located in Houston, Texas. The floor systems consist of one-way pan joists slabs supported in one direction by beams located on column lines A through F. In addition, beams are located on column lines 1 and 4 as part of the lateral force resisting system. The design loads for the floor (in addition to the self-weight) include a superimposed dead load (SDL) of 20 psf to account for moveable partitions, ceiling panels, etc. and a superimposed live load (LL) to be determined from ASCE 7-95. In addition, a 0.5 kip/ft. wall load is applied around the building perimeter. The design loads for the roof (in addition to the self-weight) include a superimposed dead load (SDL) of 10 psf. Overview of Required Design: A. Design the continuous beams of the first floor on column lines D and E of the second suspended floor assuming that they support the one-way pan joist floor system (3 parts). B. Design the slab of the second suspended floor as a one-way pan joist system supported in one direction on column lines A through F (3 parts). C. Design and detail the columns for all three stories for the location where column lines E and 2 intersect (1 part). D. Design the roof system as a two-way slab without beams (1 part). E. Design the footing for the column on column lines E and 2 (1 part). Follow detailed instructions on separate assignment sheets!!!
