Below are some descriptive load categories encountered in PEMB Software per Metal Building Software, Inc. Thanks to Dean T. Jorgenson for his help!
BASIC REACTION REPORT
Reactions are represented according to the type of load for each column location. The load type is represented with a short description or abbreviation. The descriptions are defined below.
DL = Dead
CL = Collateral
LL = Live
SL = Snow
Drift = Snow Drift
Slide = Sliding Snow
WL1 = Wind 1 Left [with positive internal pressure, +GCpi]
WR1 = Wind 1 Right [with positive internal pressure, +GCpi]
WL2 = Wind 2 Left [with negative internal pressure, -GCpi]
WR2 = Wind 2 Right [with negative internal pressure, -GCpi]
LnW1 = Longitudinal Wind, case 1
LnW2 = Longitudinal Wind, case 2
WP = Wind Pressure
WS = Wind Suction
SeisL = Seismic Left
SeisR = Seismic Right
LnSeis = Longitudinal Seismic
Temp = Temperature change
======================================================================
LnW1_L2E = Longitudinal Wind, case 1, Wind Left Edge Zone 2E
LnW1_R2E = Longitudinal Wind, case 1, Wind Right Edge Zone 2E
LnW2_L3E = Longitudinal Wind, case 2, Wind Left Edge Zone 3E
LnW2_R3E = Longitudinal Wind, case 2, Wind Right Edge Zone 3E
E#PAT_LL * = Endwall Pattern Live
E#PAT_SL * = Endwall Pattern Snow
E# - Endwall number
1 - Left endwall
2 - Right endwall
* - Auxiliary Load Id
F#PAT_LL * = Rigid Frame Pattern Live
F#PAT_SL * = Rigid Frame Pattern Snow
F# - Rigid Frame Id
* - Auxiliary Load Id
E#UNB_SL_L = Endwall Unbalanced Snow Left
E#UNB_SL_R = Endwall Unbalanced Snow Right
F#UNB_SL_L = Rigid Frame Unbalanced Snow Left
F#UNB_SL_R = Rigid Frame Unbalanced Snow Right
F#CRANEA* = Crane loading, single crane
F# - Frame number
A* - Auxiliary Load Id
F#CRNAM $ CRN - Crane loading
F#CRNA2 $ A2 - Two largest cranes in any aisle
F#CRNAM $$ AM - Simple maximum size in one aisle
F#CRNA $$ BM - Largest crane in each aisle for two adj. aisle
F#CRNBM $ C2 - Two largest crane in any aisle plus one crane in
F#CRNC2 $ any non-adjacent aisle. Also single crane at
F#CRNBM $ C2 location and double crane at other location
F#CRN B $$ $,$$ - Id associated with crane combinations
F#CRN C $$
