Abstract The number of bridges approaching or exceeding their initial design life has been increasing dramatically. Meanwhile, are withstanding an ever-increasing traffic volume, both in and weight vehicles. Analytical numerical models can predict bridges’ response to loads ultimate capacity with low uncertainties; however, such uncertainties increase as age due deterioration mechanisms. Non-de...

Low-power radio frequency (RF) chip transceiver technology and the associated structural health monitoring platforms have matured recently to enable high-rate, lossless transmission of measurement data across large-scale sensor networks. The intrinsic value of these advanced capabilities is the allowance for highquality, rapid operational modal analysis of in-service structures using distribute...

The long-term assessment of large civil infrastructures such as prestressed concrete bridges is a challenging task. The real time history related to the phased construction, the influence of the adopted construction method, the characterization of the employed concrete and the environmental conditions are crucial aspects for accurate predictions based on Finite Element Models. Data from long-te...

This article studies a concrete hollow slab simply supported-continuous actual engineering project in certain city. Before the reinforcement of bridge, there were cracks and exposed rebars, etc. In order to ensure safe operation method was adopted, prestressed steel strands are used convert simple-supported structure into continuous structure, thereby improving structural load-bearing capacity ...

the current study is focused on strengthening of reinforced concrete (rc) beams using cfrp straps installed in pre-cut grooves. the method which is referred as near surface mounted (nsm) benefits considerable advantages in comparison with the conventional externally bonded reinforcement (ebr) method and provides better normal and shear stress transfer between the frp and concrete substrate. the...

Taking a prestressed concrete box girder as the research object, aiming at problem that bridge durability is reduced due to appearance of temperature cracks in girder, this paper adopted different types heat insulation materials, and theoretically analyzed structural field under high difference low environment from aspects whether source was set inside which provides reference for technical app...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...
