We have proposed the trusses with eccentric joints to improve the post-buckling behavior. It is confirmed that the trusses with eccentric joints show stable behavior, although their initial stiffness and ultimate strength are not so high as those of ordinary trusses. In this paper, loading tests and numerial analyses are carried out to investigate the effect of lattice patterns (warren or double-warren) on ultimate strength and plastic deformation behavior of truss beams with several types of eccentric joints. As a result, double-warren trusses with eccentric joints show stable behavior, keeping their load bearing capacity high enough.
