Effect of Seismic-Induced Bearing Uplift of a Cable-Stayed Bridge
Publisher: American Society of Civil Engineers
Abstract: In the past, seismic-induced bearing uplift of cable-stayed bridges was seldom recognized or valued, and a conventional sliding bearing, which cannot resist uplift forces, was often used for cable-stayed bridges. In this ...
Experimental Verification of a Cable-Stayed Bridge Model Using Passive Energy Dissipation Devices
Publisher: American Society of Civil Engineers
Abstract: To investigate the efficiency of passive energy dissipation devices in protecting cable-stayed bridges from severe damage when subjected to high-intensity ground motions, a 1/20-scale bridge model from a typical medium-span ...
Multilevel Performance Classifications of Tall RC Bridge Columns toward Postearthquake Rehabilitation Requirements
Publisher: American Society of Civil Engineers
Abstract: This study aims at developing appropriate multilevel performance classification of tall RC bridge piers for seismic design. A new performance classification toward postearthquake rehabilitation requirements is presented. ...
Natural Frequency of Railway Girder Bridges under Vehicle Loads
Publisher: American Society of Civil Engineers
Abstract: To investigate the natural frequency of a railway girder bridge under vehicle loads, two methods are presented. First, the natural frequency of a railway girder bridge under vehicle loads is obtained by solution of the ...
Vibration Control of Railway Bridges under High-Speed Trains Using Multiple Tuned Mass Dampers
Publisher: American Society of Civil Engineers
Abstract: In this paper, multiple tuned mass dampers (MTMDs) are considered for suppressing the vibration of railway bridges under high-speed trains. The interaction equations of motion between the vehicle and the bridge with MTMDs ...
Performance Test of Energy Dissipation Bearing and Its Application in Seismic Control of a Long-Span Bridge
Publisher: American Society of Civil Engineers
Abstract: Energy dissipation bearing (EDB) is a conventional steel bridge bearing in connection with well designed mild steel dampers. Seismic performance test was undertaken for both damper units and a prototype bearing, and the ...
Treatment of <i>P</i>-Δ Effects in Displacement-Based Seismic Design for SDOF Systems
Publisher: American Society of Civil Engineers
Abstract: The displacement-based seismic-design (DSD) methods, owing to their simplicity and efficiency, have been more and more recognized in structural seismic-research communities during the past few years. However, the dynamic
Shake Table Test on a Long-Span Cable-Stayed Bridge with Viscous Dampers Considering Wave Passage Effects
Publisher: ASCE
Abstract: This work focused on the damping effectiveness of additional longitudinal viscous dampers employed for seismic control of long-span cable-stayed bridges considering wave passage effects. A 1/35-scale physical model scaled ...
Seismic Performance of Self-Centering Bridge Piers with Rocking Mechanical Hinges
Publisher: ASCE
Abstract: A rocking column has excellent earthquake resistance and post-earthquake recovery capacity. However, concrete spalling or crushing easily occur at the rocking interface due to local high compression stress. In this paper, ...
