A floor slab 100 mm thick is cast monolithically with beams 250 mm wide 450 mm deep spaced 1.2 m on centers, on simple supports over a span of 5.0 m. The floor supports a superimposed service dead load of 1.0 kPa and service live load of 2.1 kPa. Using f. 21 MPa, long bar fy = 415 MPa, calculate the following: 1. Factored uniform load on a typical interior beam in kN/m using load factors of 1.2 for dead load and 1.6 for live load. C. 11.028 Effective flange width of a typical interior beam in mm.

A rectangular reinforced concrete beam has a cross-section dimensions b=400mm andoverall depth h= 800mm. The beam as shown in the image below carries asuperimposed dead load of 12 kN/m (excluding the self-Weight of the beam) andspecified live load of 20 kN/m. The beam has a compressive strength of 30Mpa andreinforcement yield strength of 400 Mpa a) What is the self weight of the beam? b) What is the modulus of elasticy and yeild strain of reinforcement
