Example CVEG 4303: Reinforced Concrete I One-Way Slabs A 5" thick concrete slab is reinforced for tension with #4 bars spaced at 7". The effective depth is 4" Grade 60 bars and 8,ooo psi concrete will be used. 1.) Determine the design bending strength (фМп) of the slab. 2.) Check that ACI requirements for rebar strain, rebar spacing, and minimum reinforcement are met (ACI 7.3.3.1, ACI 24.3.2, and ACI 7.6.1.1 respectively). Note: Do not need to check temperature and shrinkage...

A 5 in thick simply supported
reinforced concrete one-way slab is part of a roof system. It is
supported by two masonry block walls, as shown below. Assume a
superimposed dead load (roofing, insulation, ceiling, etc.) of 15
psf and a roof live load of 30 psf. Check the adequacy of the slab,
including the required shrinkage and temperature reinforcement. Use
= 4,000 psi and = 60,000 psi.

Name: Date: 2. (+35) Design a typical interior tension-reinforced T-beam to resist positive moment. Beam dimension is given. The service loads are 150 psf dead load (doesn't include the beam weight) and 350 psf live load. The beam is on a simple span of 20 ft. Use f:=4000 psi for strength concrete and fy=60000 psi for steel reinforcement. 8-0* (typ.)

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...

Using Principles of Structural Design 2nd Edition... A 81/2 in. thick one-way slab interior spans 10 ft. It was designed with the reinforcement of #6 size bars at 6.5in. on center, to be placed with a cover of 0.75in. However, the same steel was misplaced at a clear distance of 2in. from the bottom. How much is the reduction in the capacity of the slab reduced to carry the superimposed live load in addition to its own weight? f'c=4,000 psi,...
