when I apply UniformExcitation and groundMotion????,
because if I derivate two times displacement history and then apply it to my model with "UniformExcitation -accel" and then compare it with groundMotion apply directly displacement history I obatined the same drift but not the shear reaction base why?(it is the same model and materials). any help¡
thanks you.
if you get the exact same drifts you should be getting the exact same forces .. record the node displacements, add ground to relative and see if they are also the exact same.
