Chapter 10

1997 UBC Design Load Combinations
This chapter defines the default 1997 UBC concrete shear wall
design load combinations. You may use the default shear wall
design load combinations for your design, or you may define
your own design load combinations, or you can use both default
combinations and your own combinations. You can modify the
default design load combinations and you can delete them if you
wish.

Default Design Load Combinations
The ETABS automatically created design load combinations for
concrete shear wall design based on the 1997 UBC are given by
Equations 10-1 through 10-10.

1.4ΣDL Eqn. 10-1

1.4ΣDL + 1.7(ΣLL + ΣRLL) Eqn. 10-2
