![]() ![]() The verticals may get high bending curvature if the chords are much stiffer in bending than the verticals and you get differential creep/shrinkage. Even if you had a full web, a girder just typically cambers with PT in the bottom flange and this structure has less internal restraint than a girder.Įven with a vierendeel, the truss will still cambers. You don't have restraint from the top chord to act as enough of a strong back to create significant shears. You can call it a truss or frame (although by far, the stiff load path is the truss). The creep and shrinkage does not create a significant shearing force at the end joints. If the bottom chord shrinks relative to the rest of the truss, it will just camber up. ![]() ![]() Also, there is no significant restraint from the joints or top chord. So you have to look at the relative movement/shortening. The top chord and diagonals shrinks/creeps as well. ![]()
