Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

The dynamic properties of bridge girders depend on the design solutions, namely replacement roadway slab by orthotropic, deviation from standard solutions in formation longitudinal schemes, and use a new type supports causing dissipation vibration energy gyropendulum effect.The control for with regard to multifactorial defects, is characterized ignoring shock dampers vehicles moving roadway. In...

Abstract Aerodynamic characteristics of long-span bridges with box girders have been investigated widely, and this paper presents a study on cable-stayed bridge two in parallel arrangement. Computational fluid dynamics (CFD) numerical simulations were adopted to analyze the aerodynamic interference between upper lower girders. After checking reliability model, different angles attack distances ...

Linac beams in the Stanford Linear Collider (SLC) were driven into oscillation by transverse vibration of lattice quadrupoles at about 7 Hz. These quadrupoles are centered on 12-meter support girders located early in the linac. The vibrations were caused by ground motion at the 0.06 l.tm level which was amplified in the accelerator supports up to 5 pm. Seismic and support vibration measurements...

One strong constraint in ATLAS is the easy and fast access to the Tile calorimeter readout without any destructive interference with the rest of the detector. Therefore the drawer system has been designed to place all PMTs and associated electronics on a movable system inside the TILECAL girders which provide both, the structural support to the individual modules and the solenoid return ux. In ...

This study presents a two-step FE model updating approach for health monitoring and damage identification of prestressed concrete girder bridges. To reduce the effects modeling error in process, first step, modal-based is used to estimate linear parameters mainly related stiffness boundary conditions material properties. In second time-domain carried out using acceleration data refine accountin...
