Span: ft
E: ksi
I: in4
Overhang Left: ft
Overhang Right: ft
Fixed Left: Disables the left overhang and sets value to 0 if selected.
Fixed Right: Disables the right overhang and sets value to 0 if selected.
Additional Interior Roller Support Locations:

(The 6 Simplified ACI patterns will be used when the number of patterns exceeds 63 (6 spans) full general patterning is factorial)

R1 ft
Off Pattern Factors

Typically 0 for L, Lr, and R and 0.5 for S

Off Patterns of 1 will result in no patterning for that load type

Ultimate Combinations for Shear and Moment (ULS):
f1 : other L.
f2 : Other roof configurations.
Auto Reverse Lateral Loads : Only applies to Generated Combos.
User Ultimate Combinations (ULS):

Note: Set all factors to 0 to ignore user defined ULS Combos.

Supported Load Types:
D
Dead Load
F
Load due to fluids with well-defined pressures and maximum heights. For BCBC 2018 F represents live load due to fluids in tanks.[Sentence 4.1.3.2(6)]
L
Live Loads
H
Load due to lateral earth pressures, ground water pressure or pressure of bulk materials.
Lr
Roof live load. For BCBC 2018 Lr represents Live loads due to storage areas, equipment areas, or service rooms. [Sentence 4.1.3.2(7)]
S
Snow load
R
Rain load. BCBC 2018 rain loads are not considered for the automatically generated combinations.
Wx
Wind Load in the X or 1 direction.
Wy
Wind Load in the Y or 2 direction.
Ex
Vertical Seismic Load in the X or 1 direction as defined in Section 2.3.6 of ASCE 7.
Ey
Vertical Seismic Load in the Y or 2 direction as defined in Section 2.3.6 of ASCE 7.
