Hello all,
I am trying to understand when we have to consider both axis for dimensioning of Elastomeric bearings. Most of the examples I see take in account only one (the principal rotation i.e. vertical to the bridge's longitudinal axis).
Now, about the shear strain due to rotation for a rectangular (AASHTO LFRD 14.7.5.3.3-6) :
how do we combine the shear deformation resulting from rotation in both axis ? Do we get a resultant shear and then check this value with the limits ?
Has anyone done it before ?
Thanks
Antony
