I am currently looking at a set of truss layouts produced by our truss manufacturing partner for a residential building project. I have reason to believe these layouts are generated using Alpine (Intelliview?) software. In any case, the design summary contains abbreviations which I cannot understand since I do not have a copy of the software. Please see below:
According to this document R, U and W stand for reaction due to design load, uplift due to wind load and bearing width, respectively. TCLL, TCDL, BCLL and BCDL stand for top chord live load, Top chord dead load, Bottom chord live load and bottom chord dead load. However I cannot for the life of me determine what Rw, Rh, RL and NCBCLL stand for. Any ideas?
