Abstract This study employs the finite element-based CSiBridge v.20.0.0 software to examine response of a single-cell prestressed box-girder bridge subjected Indian loading conditions. The analyses is carried out on simply supported considering specifications Road Congress (IRC) 6:2017, IRC 18:2000 and 21:2000. An existing model skewed validated with published one. A convergence conducted for d...

To improve the stability of the magnet-girder assemblies in the ESRF storage ring, vibration investigations have been carried out for in situ magnet-girder assemblies and a prototype. Characterisation tests were performed : operating response measurements, static stiffness measurements, modal testing. A finite element modelling (FEM) is being carried out for the prototype assembly. First result...

Introduction: Despite the fact that, in recent years, construction of long-span bridges has been extensively developed, cases bridge structures buckling wind still occur, but issue their interaction with not sufficiently studied. Purpose study: We aimed to improve structural integrity and operational safety by conducting a computational experimental study on effect various designs aerodynamic d...

Transverse steel damper (TSD) is a promising passive control device used for seismic isolation and has been validated to feasibly balance the girder transverse displacement inertial force in cable-stayed bridges. However, TSD system, pounding could occur at locations of tower legs when gap size insufficient accommodate girder-support relative under major earthquakes. can significantly affect dy...

Abstract The long-span bridge is highly sensitive to wind loads, and their random vibration response under static deformation fluctuating load are relatively complex. analysis of jitter has become a key issue in the design. Taking Hanjiatuo Yangtze River Bridge chongqing-lichuan railway as engineering background, influence different aerodynamic admittance functions on main girder studied throug...

Single-track railway bridges are susceptible of experiencing high levels vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply supported bridges. problem can compromise safety trains and increase maintenance costs track. The main objective this work to investigate influence ballasted track dynamic behaviou...

Infrastructure development is the very important for any Country. Highway’s infrastructure comprises two part say Roads and Bridges, supplementary to each other. In modern projects of structures increased about 40% 50% which have big influence complete project within targeted span period. As per site condition aesthetic requirement, there are several types bridges. Bridges different type supers...
