A floor is to be supported on hardwood timber joists that are spaced at 0.5m centres and span 5.0m. The joists support flooring 20mm thick and an applied live load of 2kN/m2
Design a typical joist 50mm wide
Given data;
Density of timber = 800kg/m3
Bending Stress limit = 11.0 MPa
Shear Stress Limit = 1.0MPa
Youngs Modulus = 10.5 x 10^3 MPa
