Hi,
I'm wondering if CONSPAN considers 90% the truck load when running double truck as per AASHTO LRFD 3.6.1.3 for negative moments or does it take the full truck loads?
AASHTO 3.6.1.3:
"For negative moment between points of contraflexureunder a uniform load on all spans, and reaction atinterior piers only, 90 percent of the effect of two designtrucks spaced a minimum of 50.0 ft between the leadaxle of one truck and the rear axle of the other truck,combined with 90 percent of the effect of the designlane load."
Thanks.
Thank you for the answer Vinay.

Hi ,
Conspan does considers 90% of the truck load when running double truck as per AASHTO LRFD 3.6.1.3 for negative moments.The application of 90% of the negative moment as per AASHTO code is hard coded in the program.
Please let me know if you need any additional information.
Thanks & Regards,
Vinay
