Sizing Joists and Rafters

In civil engineering and building construction, joists and rafters are the major components including beams and columns. Almost every structural construction including buildings, skyscrapers, bridges, commercial complexes, and so on makes use of joists and rafters to provide structural integrity to the building. Joists are primarily thick long pieces of metals, concrete, or wood that are used to support the floor and ceiling. On the other hand, rafters form the major component of pitched roofs, which are a series of sloped long pieces extending from a ridged area that makes contact with the plane area of the wall. They account for the load-bearing of the building along with the beams.

Question

Determine the theoretical spacing of a 75 mm
x 200 mm x 3.4 m floor joist to a dead load of
2300 M/m? excluding its own weight and live
load of 1800 N/m. Deflection is limited to
1/360 of the span. Unit weight of wood is 7.5
kN/m° and Fb = 15 MPa, Fv = 0.96 MPa, and E
= 13 400 MPa.
