Given The Reinforced Concrete Floor System Below Determine The Following

Calculate the total dead weight of the beam.

Given the reinforced concrete floor system below determine the following.

The span is 25 feet out of the page. Two way flat plate concrete floor system analysis and design the concrete floor slab system shown below is for an intermediate floor to be designed considering partition weight 20 psf and unfactored live load 40 psf. The span is 25 feet out of the page. A the design flexural strength phi m n at the midspan of an edge beam l beam b the design flexural strength phi m n at the midspan of a typical interior beam t beam assume fc 5500 psi and grade 60 reinforcement.

The orthographic views on the following page of the same floor system are. For d and for unit weight of concrete. Ec w 0 043 fc 1 5 c fc 28 day compressive strength in mpa wc unit weight of concrete in kg m3 for normal weight concrete. It consists of uniformly spaced concrete ribs spanning in one direction reinforced concrete slab constructed monolithically with ribs and beams which are spanning between columns.

The span is 25 feet out of the page. Characteristic material properties o concrete 25 mpa o reinforcement 450 mpa o main reinforcement steel y12 moderate exposure conditions slab thickness 175 mm calculate the required area of reinforcement in the short and long span directions of the slab. Plan view of floor system n elevation view it s important to have a clear picture in one s mind of the concrete structure represented by the 2d sketches above. Given the reinforced concrete floor system below determine the following.

A the design flexural strength phi m n at the midspan of an edge beam l beam b the design flexural strength phi m n at the midspan of a typical interior beam t beam assume f c 5500 psi and grade 60 reinforcement. Flat plate concrete floor system does not use beams between columns or drop panels and it is usually suited for lightly. One way joist floor system. A typical reinforced concrete floor system is shown in the sketches below.

A the design flexural strength phi m n at the midspan of an edge beam l beam b the design flexural strength phi m n at the midspan of a typical interior beam t beam assume f c 5500 psi and grade 60 reinforcement. Reinforced concrete floor system a reinforced concrete floor of a building comprises parallel reinforced concrete beams supporting and cast integrally with a reinforced concrete slab as shown in the diagram below. Here b is width of beam and d is depth of beam. Given the reinforced concrete floor system below determine the following.

Substitute 0 3 kips ft for sw and 1 5 kips ft for dl. For b 12 in. Dimensions are given in separate tables provided along with the assignment brief. Ec 4700 fc fc 28 day compressive strength in mpa wc unit weight of concrete in kg m3 reinforcing bars grades and strength of reinforcing bars non.

Calculate the self weight of the beam sw using the relation. Here dl is dead weight applied on the beam and sw is self weight of the beam. Given the reinforced concrete floor system below determine the following. Concrete properties modulus of elasticity for concrete weighing from 1 500 to 2500 kg m3.

Nominal live load 6 5 kn m2 floor finishes 1 0 kn m.
