چکیده
In order to address the difficulty in determining seismic damage probability of continuous girder bridges under construction, vulnerability analysis method construction state is proposed this study. Firstly, taking a long-span prestressed concrete composite box bridge with corrugated steel webs (OSW) as an example, finite element models (FEMs) dynamic calculation different phases cantilever are simulated by OpenSEES. Secondly, selecting reasonable waves and intensity measures, non-linear time-history carried out, followed demand parameters indexes suitable for proposed. Finally, probabilistic model (PSDA) during stage constructed using “cloud method”, curves piers temporary bearings established evaluate performance stage. The results indicate that increases progress construction. initial formation structure sudden change size segmental correspond high damage, protection measures should be strengthened state. Moreover, significantly higher components compared completed after it built.

Theoretical and Experimental Study on Natural Frequency of Externally Prestressed Box-Girder with Corrugated Steel Webs
Abstract: Based on the characteristics of box girder with corrugated steel webs, the existing prestressing force, the effect of shear deformation of composite girder on the deflection, “folding effect” in longitudinal direction of corrugate steel webs and the arrangement of external tendons were considered comprehensively. With the experiment results of five literatures integrated, N/fcA (the a...
متن کاملThe Stress-related Damping Ratio of Box Girder with Corrugated Steel Webs
In this paper, the stress-related damping ratio formula of box girder with corrugated steel webs is introduced. Using response spectrum method, an iterative algorithm is proposed to calculate the seismic response and the stressrelated damping ratio under different seismic intensities. Based on a simply supported composite box girder bridge with corrugated steel webs, the stress-related damping ...
متن کاملOptimization of Precast Prestressed Concrete Bridge Girder Systems
60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

Seismic Vulnerability assessment of concrete railway bridge using nonlinear analyses
Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...
