Hi
I am designing combined foundation with Staad.foundation V8i (ver 5.3) for pipe rack structure. I have open frame structure and most of the time
the stability checks ( Over turning and Sliding checks) governs the design for the size of the foundations for the open frame structure. I have noticed that
combined foundation design is capturing only overturning check. It is not checking the sliding check for the combined footing. In my case, we are
providing liner under the foundations. Thus, foundation become critical against sliding. Please advise, when Bentley will incorporate this
stability check for combined foundation design. I have also noticed that both stability checks ( Over turning and Sliding checks) are
available for the Isolated footing design in Staad.foundation....Please also incorporate in combined foundation design...Thanks
