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 کاملSeismic Fragility Assessment of Steel SMRF Structures under Various Types of Near Fault Forward Directivity Ground Motions
In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...
متن کاملSeismic Rehabilitation of Liquid Storage Tanks using Friction Pendulum Base Isolation subjected to the Near-Fault Ground Motions
Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...
متن کاملSeismic Behavior of Jacket Offshore Platform Subjected to Near and Far Field Ground Motions
Offshore structures such as jacket platforms have to inevitably be designed against sever environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...
متن کاملsemi-active fuzzy control of structures subjected to near-fault ground motions having forward directivity and fling step using friction damping system with amplifying braces (fdsab)
in this paper, the consequences of well-known characteristics of near-fault ground motions, forward directivity and fling step, on the seismic response control is investigated. an integrated fuzzy rule-based control strategy for building structures incorporated with semi active friction damping system with amplifying braces (fdsab) is developed. the membership functions and fuzzy rules of fuzzy...
