Abstract:
A method for constructing a truss includes selecting three or more chord elements (two or more upper chord elements and one or more lower chord elements) and one or more web elements. The selecting of the components includes estimating a first change in length for each of the two or more upper chord elements and estimating a second change in length of each of the one or more lower chord elements, the first change in length and the second change in length in response to changes in conditions to which the truss is exposed. The one or more web elements are selected from the plurality of wood members to compensate for the deformation caused by the first change in length and the second change in length.
