General Notes (continued)
<br /> Key to Terms:
<br /> Information provided on drawings reflects a summary of the pertinent information required for the truss design. Detailed
<br /> information on load cases, reactions, member lengths, forces and members requiring permanent lateral support may be
<br /> found in calculation sheets available upon written request.
<br /> BCDL= Bottom Chord standard design Dead Load in pounds per square foot.
<br /> BCLL= Bottom Chord standard design Live Load in pounds per square foot.
<br /> Des Ld=total of TCLL, TCDL, BCLL and BCDL Design Load in pounds per square foot.
<br /> HORZ(LL)= maximum Horizontal panel point deflection due to Live Load, in inches.
<br /> HORZ(TL)=maximum Horizontal panel point long term deflection in inches, due to Total Load, including creep
<br /> adjustment.
<br /> HPL=additional Horizontal Load added to a truss Piece in pounds per linear foot or pounds.
<br /> U#= user specified divisor for limiting span/deflection ratio for evaluation of actual Udefl value.
<br /> Udefl =ratio of Length between bearings, in inches, divided by the immediate vertical Deflection, in inches, at the
<br /> referenced panel point. Reported as 999 if greater than or equal to 999.
<br /> Loc= Location, starting location of left end of bearing or panel point(joint)location of deflection.
<br /> Max BC CSI = Maximum bending and axial Combined Stress Index for Bottom Chords for of all load cases.
<br /> Max TC CSI = Maximum bending and axial Combined Stress Index for Top Chords for of all load cases.
<br /> Max Web CSI=Maximum bending and axial Combined Stress Index for Webs for of all load cases.
<br /> NCBCLL= Non-Concurrent Bottom Chord design Live Load in pounds per square foot.
<br /> PL=additional Load applied at a user specified angle on a truss Piece in pounds per linear foot or pounds.
<br /> PLB=additional vertical load added to a Bottom chord Piece of a truss in pounds per linear foot or pounds
<br /> PLT=additional vertical load added to a Top chord Piece of a truss in pounds per linear foot or pounds.
<br /> PP= Panel Point.
<br /> R=maximum downward design Reaction, in pounds, from all specified gravity load cases, at the indicated location(Loc).
<br /> -R= maximum upward design Reaction, in pounds,from all specified gravity load cases, at the identified location (Loc).
<br /> Rh = maximum horizontal design Reaction in either direction, in pounds, from all specified gravity load cases, at the
<br /> indicated location(Loc).
<br /> RL= maximum horizontal design Reaction in either direction, in pounds, from all specified non-gravity(wind or seismic)
<br /> load cases, at the indicated location(Loc).
<br /> Rw=maximum downward design Reaction, in pounds, from all specified non-gravity(wind or seismic)load cases, at the
<br /> identified location(Loc).
<br /> TCDL=Top Chord standard design Dead Load in pounds per square foot.
<br /> TCLL=Top Chord standard design Live Load in pounds per square foot.
<br /> U =maximum Upward design reaction, in pounds,from all specified non-gravity(wind or seismic) load cases, at the
<br /> indicated location(Loc).
<br /> VERT(CL)= maximum Vertical panel point deflection in inches due to Live Load and Creep Component of Dead Load in
<br /> inches.
<br /> VERT(LL)=maximum Vertical panel point deflection in inches due to Live Load.
<br /> VERT(TL)=maximum Vertical panel point long term deflection in inches due to Total load, including creep adjustment.
<br /> W=Width of non-hanger bearing, in inches.
<br /> Refer to ASCE-7 for Wind and Seismic abbreviations.
<br /> Uppercase Acronyms not explained above are as defined in TPI 1.
