Seismic Response and Analytical Fragility Functions for Curved Concrete Box-Girder Bridges
Curved bridges are constructed to conform to geometric constraints resulting from traffic and structural restrictions. They are different from their straight counterparts since the response coupling in the longitudinal and ...
Analytical Fragility Curves for Horizontally Curved Steel Girder Highway Bridges
Reconnaissance studies following recent significant earthquakes have revealed the seismic vulnerability of curved bridges. Curved steel bridges are widely utilized as important components of transportation networks across ...
Seismic Response Control Of Structures Using Semi-Active and Passive Variable Stiffness Devices
Controllable devices such as Magneto-Rheological Fluid Dampers, Electro-Rheological Dampers, and controllable friction devices have been studied extensively with limited implementation in real structures. Such devices have ...
Development of Magnetorheological Elastomer System for Adaptive Vibration Isolation
ABSTRACTThis main objective of this study was focused on a proof-of-concept study of the performance of an adaptive bearing (AB) system under traffic and wind loadings, featuring magnetorheological elastomers (MREs). MREs ...
Effect of Torsional Ground Motion Component on Floor Acceleration Response in Flexible SMRF Buildings
This preliminary study investigates the effect of torsional components of the ground motions (TGM) on the floor acceleration response of flexible special moment resisting frame (SMRF) buildings. For this purpose, computational ...
SEISMIC RESPONSE ASSESSMENT AND RECOMMENDATIONS FOR THE DESIGN OF SKEWED HIGHWAY BRIDGES
Seismic vulnerability of highway bridges remains an important problem and has received increased attention as a consequence of unprecedented damage observed during several major earthquakes. A significant number of research ...
Damage Avoidance Design of Special Truss Girder Frames with Energy Dissipation Devices
An innovative detail that facilitates the use of energy dissipating devices, such as Buckling Restrained Braces (BRBs), is proposed for Special Truss Moment Frames (STMFs). The configuration of the proposed Special Truss ...
Preliminary Investigation of Torsional Ground Motion Effects on the Response of Seismically Isolated Buildings
This paper compares the response of the low-rise seismically isolated building with and without torsional ground motion. The response of the building under pulse-like and non-pulse like ground motions are also compared. ...
