Hi there,
I'm checking a design calculation for an abutment on spread footings done in LEAP RCPier. I couldn't find any information in the user manual or input/analysis tabs to determine how bearing pressure is calculated for a wall bearing on soil or rock. Note, depending on this criteria, AASHTO requires bearing stress to be determined based on a uniform distribution (soil) or linearly distributed (rock).
Any help on this matter would be appreciated.
Thanks
Also if the user wants to input maximum Soil reaction manually then that information can be inputted in the Footing TAB --> Reaction Parameters --> user specified maximum Soil reaction.
Whatever value inputted here by the user will be used for the design of the footing. Currently user cannot input if the spread footing is on Rock.
