There is growing use of FRP composite materials in the civil infrastructure for rehabilitation of deficient bridge components including deck slabs and girders. However assessment of the effectiveness of rehabilitation over time and monitoring the progression of damage or change in load paths between the structural components, caused by sequential strengthening of the components, has not been un...

The vibration of components of the NLC linac, such as accelerating structures and girders, is being studied both experimentally and analytically. Various effects are being considered including structural resonances and vibration caused by cooling water in the accelerating structure. This paper reports the status of ongoing work.

The long-span double-deck truss girder bridge has become a recommend structural form because of its good performance on traffic capacity. However, the vortex-induced vibration (VIV) characteristics for girders are more complicated and there is lack related research. In this research, wind tunnel tests were utilized to investigate VIV large-span bridge. Meanwhile, suppression effect aerodynamic ...

The excessive deflection of large-span cantilever cast prestressed concrete (LCCPC) box girders has always been a complex problem to be solved in bridge engineering. To analyze the effect shear deformation at segmental joints on LCCPC girders, comparison tests were carried out three (PC) I-girders with and PC I-girder without joints, finite element simulation method was proposed based tests. Su...

Abstract Sinusoidal corrugated web girders, which are in the focus of current paper, have been increasingly used past years civil engineering applications due to economical design. Recently, a number experiments dealing with particular behaviour this girder type carried out at room temperature, while structural elevated temperature has not widely analysed and requires further investigation clar...

In steel trapezoidal box girder bridge systems, the U-shaped steel girder is designed to act compositely with the concrete deck to form a closed box for live loading. During the construction stage, however, the behavior is not well understood. The usual practice of assuming the system to be non-composite during construction requires substantial top flange bracing to form a quasi-closed box sect...

The application of trapezoidal corrugated plate as the web for girders, thanks to a number favorable features, modernizes manufacture steel-concrete composite and hybrid structures provides an alternative, competitive structure small, medium large span beams. However, traditional headed stud shear connectors on top flange can be considered obsolete in many ways. By embedding steel concrete slab...
