i am modelling RCC single span bridge in ANSYS workbench and i want to model the supports of bridge using spring constant values of 2.4kN/mm in X direction, 2.4kN/mm in Y direction, 469kN/mm in Z direction (vertical) but if i see elastic support in ANSYS it shows only one value may be vertical in unit like (kN/mm3). how can i apply 3 spring constant value which resemble the bearing pad of bridge ?
