There was temporary bracing tied to the frames that was pulling it down and pre-loading the frame. As more load was placed on the frame, it was not deflecting much, if at all. This was because all we were doing was reducing tension in the temporary bracing. Most of the load is on the frame and the deflections ...

We have a project consisting of a 300 foot span, all bolted, box truss girder, connected through moment connections to columns. We are measuring the mid-span deflection as load is added to the girder. We are in the initial stages of adding load and have seen some un-expected initial softness in the system ...
