What does this eta factor in the load combinations tabs in CONBOX do?
I'm looking for the second order quadruple eta factor.
Eta factor is basically load modifiers.
I added eta factor of 1 and i got a required of 2776.26 kips for service III load combination.
Then i changed the eta factor of 2 and then i got a required of 7373.00 for service III load combination.
