Truss combined stress index
Webtogether on site e.g. top hat attic truss. This example illustrates that the members in a truss are subjected to axial forces (i.e. tension or compression). Since members can resist axial forces more easily than they can bending forces, smaller timber sections can be used in a truss than an equivalent beam. Combined Stress Index WebCSI (Combined Stress Index) The total of axial and bending stresses as a ratio of allowable stress in truss members. The CSI ratio can be up to 0.99. Max CSI are shown on the truss design drawings. Dead Load. Any permanent load …
