چکیده
Based on an innovative high-speed railway simply supported bridge (HSRSSB) model, the potential influence of near-fault pulse-type ground motions HSRSSB is analyzed. Eighty-five original records such are imposed simulation model. The dynamic responses calculated, including girder displacement, rail pier bending moment, bearing deformation, and residual displacement. Linear regression analysis reveals relationship between response intensity measures (IMs). Moreover, six typical chosen from these eighty-five as prototypes in order to perform a pulse parameter analysis. Through artificial motion synthesis, effects parameters, amplitude, period, number, behavior investigated discussed. It concluded that depends acceleration-type IMs presents strong linear with spectral at fundamental period structure. Regarding shows positive correlation but negative period.

Seismic response analysis of high-speed railway vehicle-slab ballastless track-bridge system under near- fault pulse ground motions
This paper presents a finite element method (FEM) framework for the dynamic analysis of coupled vehicle—bridge systems under nearfield /far-field ground motions. A train car with two bogies is assumed to be represented sufficiently by a discrete, rigid multi-body system with thirty-eight degrees of freedoms (DOFs). The normal Hertzian contact theory and the tangential Kalker linear theory modif...
متن کاملWavelet-based Analysis for Pulse Period of Earthquake Ground-motions
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...

The existence of recorded accelerograms to perform dynamic inelastic time history analysis is of the utmost importance especially in near-fault regions where directivity pulses impose extreme demands on structures and cause widespread damages. But due to the scarcity of recorded acceleration time histories, it is common to generate proper artificial ground motions. In this paper an alternative ...
متن کاملVector-valued intensity measures for pulse-like near-fault ground motions
A vector-valued intensity measure (IM) is shown to account for the effects of pulse-like near-fault ground motions. This class of ground motions, which are indicated by the presence of a velocity pulse, can cause large responses in structures and their effects are not well described by traditional intensity measures such as spectral acceleration at the structure’s first-mode period, Sa(T1). It ...
