Double layer space truss grids can cause spreading member failures and progressive collapse. To improve this brittle-type post-buckling behavior, we have proposed to introduce eccentric joints in compressive chord members. In this study, structural properties of space truss grids with eccentric members are investigated by numerical analysis. Eccentric joints shed the compressive force of critical chord members to other under-stressed members, and different collapse mechanisms are formed. They make the behavior in post-buckling range stabler. In some cases, load carrying capacity of eccentric jointed trusses can be higher than that of ordinary trusses.
