Reinforced concrete design, Mechanical Engineering

You are tasked with the analysis and design of the gravity and wind framing system for a 6-story office building. A part plan of the building is attached. 

The plan dimensions of the building are 140 feet (5 bays @ 28 feet per bay) by 125 feet (5 bays @ 25 feet per bay). The story height is 13 feet. A rectangular reinforced concrete core is constructed between grids C and D and 3 and 4. The design wind pressure on the building is 20 psf. 

You are tasked with a) framing a gravity floor system constructed of reinforced concrete, b) sizing the one-way  slabs; beams on column lines  1.5,  2  and B; and column B2,  and  c) drawing details using AutoCad or similar of critical elements, to include slabs, beams (all those designed above), columns, beam-column connections, slab-to-beam connections that include rebar details (size, spacing, etc). 

Assume the following

  • A one-way beam and slab system
  • Concrete compressive strength of 3500 psi for the slabs and beams and 4000 psi for the columns and walls
  • Grade 60 rebar
  • Tied columns
  • Superimposed dead load on the floor (roof) system of 30 psf
  • Superimposed live load on the floor (roof) system of 50 psf
  • Integrity rebar details per ACI-318
