Abstract A significant proportion of existing bridges in high seismic regions were constructed prior to the 1970s. As a result poor reinforcement detailing, pre-1970s bridge columns are susceptible lap-splice or shear failure plastic region. Given economic impact retrofitting all reinforced concrete (RC) bridges, it is essential identify most vulnerable for retrofit prioritisation. Analytical f...

Most of the existing engineering structures were built in last century and have been service for decades. However, environmental degradation may lead to a reduction structural performance life. The mechanical property data full-scale structures, such as bridges, are essential health monitoring. For this purpose, five (half) reinforced concrete (RC) T-beams removed from retired 31-year-old bridg...

Mexico highway network has more than 14,000 bridges. Most of them are reinforced concrete (RC) structures. The bridges design process incorporates the use an overstrength factor that is not justified and received little attention in published works. Mexican regulations allow using for buildings range 2–3, to reduce spectra as a function selected seismic behavior factor. However, bridges, single...

Reinforced concrete (RC) bridge decks suffer from cracking damages caused by traffic loading and environmental-related defects, such as the alkali-silica reaction (ASR). These require inspections involving measuring crack width density followed essential maintenance repair works, however, there are no signs for fatigue failure. In this study, out-of-plane shear deformations which cause small de...

The existing literature mainly focuses on the research of reinforced concrete (RC) beams under a single load such as blast or impact. In this paper, slab–rib–slab RC beam, new type structure widely used in bridge structures, was taken object. explicit dynamic analysis software LS-DYNA to numerically analyze response and failure behavior I-shaped combined impact loads. For reason, an effective n...

A wireless power transfer (WPT) system transfers an alternating current (AC) from a TC (transmitter coil) to RC (receiver coil), using electromagnetic field concept. Several previous reports on WPT systems were able transmit this power, although their AC frequencies high in some kilohertz or megahertz (kHz MHz). These unable be applied directly the loads only administered direct (DC) energy aft...
