title = "NONLINEAR DAMPED RESPONSE ANALYSIS OF PLANE SOLID STRUCTURES UNDER EXTREME EARTHQUAKES USING A NOVEL IMPLICIT DYNAMIC FINITE ELEMENT PROCEDURE",
abstract = "An implicit dynamic finite element procedure with decoupled equations is adopted to simulate the nonlinear damped response of plane solid structures under extreme earthquakes in this study. The equivalent nodal secant stiffness and damping coefficient are applied to decouple the dynamic equilibrium equations so that the triangular factorization of the coefficient matrix is not required. In addition, a method is proposed to rapidly evaluate the stiffness-proportional damping nodal forces at the element level when a plane solid structure undergoes highly nonlinear dynamic behaviour. In this method the rigid body motion of the plane element is evaluated efficiently and then the pure deformation velocity is used to evaluate the element damping nodal force. As compared to the traditional finite element dynamic analysis method, the proposed method demonstrates the accuracy and efficiency in simulations of nonlinear damped response of plane solid structures under extreme earthquakes.",
