problem with softening in drucker prager

hello everybody, In the drucker prager material of opensees there is a constant To used for softening parameter delta2 is the value of constant correct that value should not be maximum tensile strength of the material where it becomes plastic please explain be the softening parameters in drucker pra...

mode shapes for 3D solid brick column

what if i want to have mode shapes of a solid bridge pier i have to model it as 2D with lumped masses and then find its mode shapes? or there is any other way in opensees through which i can get mode shapes of solid 3D bridge pier
