Seismic Performance of Benchmark Highway Bridge Installed with Passive Control Devices

In this paper, a four-storey reinforced concrete frame infilled wall structure does not meet the seismic perform target, based on the seismic behavior target of both frame and infilled wall, to carry out the study on the passive control seismic strengthen of RC infilled wall structure with attached dampers. First, two kinds of passive control strengthen schemes were put forward. Scheme 1: Dampers were installed in the in-plane direction parallel with all 1-storey infilled walls; Scheme 2: Dampers were installed in the in-plane direction parallel with all 1-storey and 2-storey infilled walls. Then to establish the two types of passive control seismic strengthen model in OpenSees, carry out the rare earthquake nonlinear time-history analysis under El Centro, Parkfield and San Fenando ground motions. Finally, in accordance with the seismic performance target quantization index of RC Frame infilled wall structure used as hospital, i.e. considering storey drift ratio limit and infilled wall damage, judge the scheme 2 can meets the seismic performance target.

Energy Absorbing

Abstract Retrofit and structural design with vibration control devices have been proven repeatedly to be feasible seismic hazard mitigation approach. To control the structural response; supplemental energy dissipation devices have been most commonly used for energy absorption. The passive control system has been successfully incorporated in mid to high rise buildings as an appropriate energy absorbing system to suppress seismic and wind-induced excitation. The considerable theses that are highlighted include vibration control devices, the dynamic behavior of devices; energy dissipation mechanism, devices installation approach and building guidelines for structural analysis and design employing vibration control devices also, design concern that is specific to building with vibration control devices. The following four types of supplemental damping devices have been investigated in this review: metallic devices, friction devices, viscous fluid devices, and viscoelastic devices. Although numerous devices installation techniques available, more precisely, devices installation approaches have been reviewed in this paper, including Analysis and Redesign approach (Lavan A/R), standard placement approach, simplified sequential search algorithm, and Takewaki approach.
