A beam 300 mm wide x 450 m deep is simply supported on a span of 7 m.
Given:
Superimposed uniformly distributed:
Dead Load- 17 kN/m
Live Load 16 kN/m
Concrete, fc' 30 MPa
Steel yield strength, fy 415 MPa
Modulus of Elasticity Steel 200 GPa
Unit weight of concrete = 23.5 kN/m³
Depth to the centroid of tension reinforcement = 68 mm from the bottom
Compute the nominal bending capacity of the section if the tension reinforcement consists of 5-25 mm dia. bars. (kN-m)
Tip: avoid rounding off the values during the solution, use shift store function of calculators to get the correct answer in 3 decimal places.
