a t-beam has the following properties; bf = 820mm, bw = 250mm, d = 470mm and tf = 100mm. Concrete compressive strength is 20.70 MPa and the steel yield strength is 414 MPa. Determine the number of bars need if MDL = 150 kN-m and MLL = 120 kN-m. Use 25 mm bar. What is the steel area needed?
Consider the cantilever beam made of reinforced concrete. Determine if the steel and the concrete withstands loads. In the piece there are 3 steel bars of 16 mm in diameter placed at the top of the section. Consider Econcrete = 25GPa, Esteel = 200GPa, σ (break, concrete) = 35MPa, σ (break, steel) = 500MPa, SFconcrete = 1.4 (safety factor of concrete), SFsteel = 1.15 (safety factor of steel).
* TIP: The allowable stress is given by σadm = σrup/SF
Compare the maximum values obtained to those allowed by the material.
