摘要

An experimental investigation of different damping devices was carried out toallow for physical or mathematical modeling of their behavior. A series of shaking table tests of a 1:3 scale reinforced concrete frame incorporating these devices were performed after the frame was damaged by prior severe (simulated) earthquakes. Several damping devices were used in this study: (1) viscoelastic; (2) fluid viscous; (3) friction (of two types); and (4) fluid viscous walls. An analytical platform for evaluation of structures integrating such devices was developed and incorporated in IDRC Version 3.2 (Kunnath and Reihorn, 1994). The experimental and analytical study shows that the dampers can reduce inelastic deformation demands and, moreover, reduce the damage, quantified by an index monitoring permanent deformations. An evaluation of efficiency of dampers using a simplified pushover analysis method was investigated as as alternative method for prediction of behavior and design. This report, first in a series, presents the evaluation of fluid viscous dampers used as additional braces in reinforced concrete frame structures.
