Given: E = 14,000 MPa. fb = 52 MPa, fs = 6.1 MPa
A house has 250 x 45 joists at 400 mm spacings that span 6 m. Assuming the total design floor pressure is 2.5 kPa (kN/m2), carry out the following tasks:
(a) Drawtheshearforcediagramshowingsignificantvalues.
(b) Drawthebendingmomentdiagramshowingsignificantvalues.
(c) Is the joist strong enough in terms of shear and bending? Justify your answer.
(d) IsthejoistdeflectionlessthantheallowablemaximumofL/300?
