1. Design of Tension Members
A member that supports axial tension loads is defined as a tension member. Tension members are simple structural elements to design, with perhaps the simplest being concentrically loaded uniform tension members, as they are nominally in a state of uniform axial stress. However, a tension member is not always connected concentrically. In many cases the fabrication of tension members is simplified by making their end connections eccentric, but this will induce bending moments which interact with the tensile loads leading to a reduction in the ultimate strength. The effect of the bending action caused by eccentric connections is dealt with in AS 4100. by introducing a correction factor k t . AS 4100 provides two criteria which a tension member must meet: (i) yield : The stress at which steel begins to deform plastically (permanent deformation starts). Up to this point → deformation is elastic (returns to original shape wh...
