This study is devoted towards evaluating seismic performance of a three-span continuous highway bridge subjected to moderate to strong earthquake ground motions in its longitudinal direction. In this regard, nonlinear dynamic analysis of the bridge based on the direct time integration approach using the 4 order Runge-Kutta method is conducted. Two types of isolation bearings are used in the ana...

Title of Thesis: EMBEDDED STRAIN SENSOR WITH POWER SCAVENGING FROM BRIDGE VIBRATION Ming Wang, Master of Science, 2004 Thesis directed by: Professor Peter C. Chang Department of Civil Engineering The Objective of this thesis is to investigate an embedded strain sensor system with power scavenged from highway bridge vibration for structure health monitoring. A power scavenging scheme is develope...

Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...

13 Vertical displacements are among the most important technical parameters to evaluate the health 14 status of a bridge structure and to verify its bearing capacity. Several methods, both conventional 15 and innovative, are used for structural displacement monitoring; no one of these does allow, at the 16 same time, precision, automation, long term and dynamic monitoring without using high cos...

In this work, the vertical motion of a simply supported railway bridge which is subjected to circulation high speed trains was studied. A system consisting two-layer beam considered model dynamics structure. The upper represents rails with sleepers and lower deck. These two beams are coupled through distributed nonlinear springs that ballast action. characteristics these elements were identifie...

We report first evidence of wakefield acceleration of a relativistic electron beam in a dielectric-lined slab-symmetric structure. The high energy tail of a ∼60  MeV electron beam was accelerated by ∼150  keV in a 2 cm-long, slab-symmetric SiO2 waveguide, with the acceleration or deceleration clearly visible due to the use of a beam with a bifurcated longitudinal distribution that serves to app...

The bending stiffness distribution of beams composed simple-span precast prestressed beams, which are made continuous by deck reinforcement at intermediate supports, is not constant. As the structure undergoes loading, slab support cracks earlier than span soffit and due to that changes along beam length. effect nonconstant on moment redistribution before yielding studied experimentally analyti...
