Question
A beam 300 mm wide x 450 m deep is simply supported on a span of 6.8 m.
Given:
Superimposed uniformly distributed:
Dead Load = 18 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 = 70 mm from the bottom
Compute the nominal bending capacity of the section if the tension
reinforcement consists of 3 - 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.
