摘要
For a lateral face of the lattice girder, defined by an upper chord and a lower chord, the triangulation comprises compression bars substantially perpendicular to the chords, oblique tension bars of smaller length connecting the top of a compression bar to the lower chord, and other oblique tension bars of greater length, also connecting the top of a compression bar to the lower chord, at a point located further ahead toward the base of the next compression bar. This triangulation is used, in particular, for the jib and counterjib elements of tower cranes.
