Doubt on Monobe Okabe Coefficients.
Doubt on Monobe Okabe Coefficients.
(OP)
I have ported the Monobe-Okabe expressions in a text to one Mathcad sheet, and I have replaced active where passive coefficient and viceversa because the labeled as active push was giving a higher value (say 2.29) than the labeled passive (say 0.6)...yet another text and AASHTO both confirm my original reference against my change.
Yet what the Monobe Okabe equations maybe saying is that once disengaged the wedge and downwards the earthquake push is bigger than when the wall in the displaceable building or retaining wall moves against the soil.
So please indicate whether the labeled active push by the Monobe-Okabe assumption is expected to be higher than the labeled passive or viceversa.
Thank you beforehand.

I see values for earthquake passive push in the ordinary static ranges, so I still think the passive Monobe-Okabe should be bigger than the active.
...so all points to that I may be taking some angle with changed sign (I think no criteria there is for some).

This may be the cause of your result.
RE: Doubt on Monobe Okabe Coefficients.
Today I have been starting some part of a design that may need the use of the formulation and have rediscovered your post ... and that the reference you give may be already more or less available for all.
I am looking forward to see what comes within, I have just downloaded it.

Thanks again, and best wishes to everyone here.
