Hysteretic Behavior of Prestressed Concrete Bridge Pier with Fiber Model
The hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier were researched. The effects of the prestressed tendon ratio, the longitudinal reinforcement ratio, and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method. The analysis show...
متن کاملAnalysis of a High-pier Railway Bridge under Spatial Stochastic Stationary and Non-stationary Earthquake Excitations
Original scientific paper The objectives of this paper are to perform a comparative analysis of the large-scale system of a high-pier railway bridge subjected to stationary and nonstationary spatially varying earthquake excitations using the pseudo-excitation method (PEM), and to estimate whether or not the non-stationary stochastic analysis of the high-pier railway bridges under tri-directiona...

متن کاملRailway Continuous Prestressed Concrete Bridge Design in Ballastless Track Turnout Zones
Laying ballastless track on railway bridges has the advantages of reducing the train noise problem, improving passenger comfort, and reducing track maintenance costs. Therefore, railway bridges with ballastless track have gradually turned into a major trend in railway systems all over the world. In Taiwan, railway bridges with ballastless track have been in use for many years, with ballastless ...
متن کاملExperimental Study of a Controlled Rocking Bridge Pier
Controlled rocking of steel braced frames has been proposed for the seismic retrofit of structures. The controlled rocking approach allows a frame to uplift from its support at the base-of-column to foundation interface while displacementbased steel yielding devices are implemented at the base location to control the response. Past studies have focused on analytical investigations of the respon...
