Passive Control Of Highway Structures: Improvement of Earthquake Resistance of PC Cable-Stayed Bridges by Hysteresis Type Damper and Tuned Mass Damper
Abstract/Contents
- Abstract
- The objective of this project is to introduce recent development, in seismic-counter measure techniques to assess analytical and experimental effectiveness, feasibility and limitations of damping augmentation devices, such as lead rubber bearings, elastometric bearings and damped resonant appendages, with respect to the seismic performance of cable-stayed bridges. To achieve this objective, emphasis was placed on: (1) the results of the USC two shake tables (4 ft x4 ft with separating distance 12 ft center-to-center) tests of a 1:100 reduced scale model of an existing Japanese cable-stayed bridge; (the Yobuko Bridge) tests were carried out without the energy absorption device and with the hysteric energy dissipation device, (2) the results of damped resonant (tuned) appendages with relatively small mass and high damping ratio using a pair of small shaking tables (at UCI) to longitudinally shake the 12-ft long bridge model of the same cable stayed in Part 1, and (3) the results of computational analysis of the prototype by the Kajima research team to improve the earthquake resistance of floating type prestressed concrete cable-stayed bridges by introducing passive vibration systems such hysteretic type devices and tuned mass damper devices.
