The Role of Structural Damping in Dynamic Response

Abstract

Almost all descriptions of damping are derived from a linear SDOF system with a viscous damper in parallel with the spring, and all damping measurements relate to energy loss per cycle of motion. Several investigators have recommended use of large damping ratios during plastic response calculations. Even small amounts of damping can significantly effect calculations in the plastic response region. Damping for plastic response can not be defined. Experimental or analytical verification for Damping during plastic response is not available. Damping should not be used when plastic response is the predominant mode.
