The paper presents a new damping model in which the inherent damping forces during inelastic vibrations are taken to be proportional to the first derivative of the restoring forces with respect to time. The model can also be interpreted as the damping forces being proportional to an estimate of the elastic component of velocity rather than to the total velocity, which includes plastic and elastic components. ![]() The G Summary Eqe Tools For Sale BS in Civil Engineering in the Philippines. The Bachelor of Science in Civil Engineering (BSCE) program is a five- year program that educates students with basic principles of Science in conjunction with mathematical and computational tools used in engineering. The model reduces to the conventional viscous damping model for elastic response but differs from it during inelastic deformations. Although the model is based on the initial properties of the structure, the resulting response is similar to that obtained by the conventional viscous approach using current properties (tangent stiffness). The new damping model is evaluated by comparisons with the response for different viscous damping models obtained by numerical inelastic time‐history analyses of a multi‐story structure subjected to different earthquake excitations.
