ABSTRACT
In order to take into account the effects of truss member continuity (for chords, in particular), joint rigidity and/or eccentricity, and loads applied between the nodes, the methods suitable for frame analysis should be used. As a result, additional or secondary moments and forces develop. A first order elastic analysis is generally adequate for technical purposes. Second order analysis is required for the elastic or inelastic range, to obtain reliable information on the ultimate capacity of the truss, and to include the effects of out-of-straightness and joint eccentricity for compression members and joint eccentricity for tension members.
