Resistant Protection of Bridges (AFPS, ), this new regulation framework enables to take advantage of latest scientific and technological advances in seismic design and analysis of structures, such as probabilistic seismic hazard evaluation, non-linear structural analysis and anti-seismic devices use. The seismic analysis of bridges with UDCMEJ under the excitation of seismic sequence is conducted on a continuous beam bridge and a probabilistic assessment is introduced in this study. Conclusions are drawn from comparing fragility curves with and without : JianĀ GuoĀ Wang, YuĀ TaoĀ Pang, WanĀ ChengĀ Yuan.

Force-based modal spectral analysis associated with behavior factor q This first set of analysis methods is nowadays probably still the most commonly used approach for seismic design of structures in most regions of the word subjected to earthquake hazard. design of bridge foundations in seismic regions, soil-structure interaction analyses are normally required. Such analyses become more complex when soils supporting the bridge foundations are liquefiable and the effects of soil liquefaction need to be : Dan Yang, Ernest Naesgaard, Peter M. Byrne.
inelastic responses of various components was proposed for use in the seismic analysis. Based on the analytical investigations and available experimental research, guidelines for the seismic analysis and design of integral abutment bridges were developed. . integration in the present dynamic analysis is Δt =1/ sec and beam elements are used for modeling each girder. Numerical Results and Discussion Model A The collision spring has been employed to carry out the dynamic response analysis of a bridge that involves collision.

The seismic response for each model was compared with conventional elastic and fixed-base models. Several soil stiffness values and earthquake records are considered for analysis. Maximum values of displacement, plastic hinge rotation, and cumulative plastic hinge rotations were noted and compared.
General foundation models are identified that are suitable for (a) modeling soil-structure interaction for the seismic analysis of bridges, (b) modifying an existing, nonlinear, seismic-bridge-analysis computer program to include a new element capable of representing such models, and (c) conducting a parametric study to assess the effect of the.
We have discussed three approaches to the modeling of pile foundations for the seismic analysis of bridges. From simple to complex these models are the impedance matrix model, the individual pile model, and the detailed model. Of these models, we consider the individual pile model to be the most useful for the routine analysis of by: 8.

INTRODUCTION The intent of this paper, is to focus on design concepts and issues related to the seismic design of pile foundation systems representative of those typically used for bridges and buildings. Pile foundations for such structures, as shown for example in Figures 1 and 2, areCited by: 1.
analytical method is the only feasible approach to develop fragility curves for bridges in this region. This report presents an analytical method for the development of fragility curves of highway bridges. The procedure for the seismic fragility analysis of highway bridges is briefly described as follows: 1.

The chapter starts with available models for the bridge deck and their role in seismic. This paper focuses on the effects of near-fault motion characteristics on the seismic performance of tall pier bridges. Using the analytical models calibrated by shake table tests, fragility.
The main purpose of seismic analysis is to understand how bridge structures respond to earthquake ground motion and how to achieve stability and strength requirements to protect human lives and assets. This course provides the basic concepts of structural dynamics and earthquake engineering and emphasizes on the importance of the main factors that control the seismic response of bridge.
