I am wondering about the warning that I got on my output file saying that "ZERO STIFFNESS IN DIRECTION 1 4 5 6" and that is the intersection node of cross bracing. I specified the bracing members as truss elements within STAAD library although example one in tutorial found in STAAD manual and had the same warning, but still I am concern for that, since they are stating that all the load in that directions will be ignored.

This has been highly discussed at the Bentely forums. I have checked, and it appears many users encountered the same issue with the Zero Stiffness in Direction X X X X". I recommend you check the answers provided by the Bentley support technicians, because this isn't a problem that could be easily fixed by anyone since STAAD.Pro requires extremely vast knowledge.
