Defining linear spring behavior with complex stiffness

Springs can be used to simulate structural dampers that contribute to the imaginary part of the element stiffness forming an elemental

structural damping matrix. You specify both the real part of the spring stiffness for particular degrees of freedom and the structural damping factor, s. The imaginary part of the spring stiffness is calculated as and represents structural damping. These data can be frequency dependent. Input File Usage:
