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...

In this paper, the rib beam bridge slabs were taken as research object. Static load and fatigue tests carried out on benchmark to determine ultimate capacity life of slabs. Then, slab was pre-damaged reinforced with polyurethane concrete. A test study performance. Based damage theory, reinforcement finite element models under different degrees established. The performance systematically studied...

Accounting for the effect of rebar depth variation is one of the most important and challenging tasks to accurately assess the condition of reinforced concrete elements using ground penetrating radar (GPR) technique. In current practices, this task is performed on the individual basis, as for each bridge deck a unique depth correction model is derived from the GPR data collected on it. It is fo...

In this work, a system is designed for monitoring the structural health of bridge deck and predicting various possible damages to this section based on measuring the temperature and humidity using wireless sensor networks, and then it is implemented and investigated. A scaled model of a conventional medium-sized bridge (of 50 m length and 10 m height, and with 2 piers) is examined for the purpo...

Structural visual inspection documentation is essential for monitoring, maintaining, rehabilitating, and reinforcing structures. Close-Range Photogrammetry (CRP) Terrestrial Laser Scanners (TLS) are cutting-edge technologies that commonly used in surveying. In this article, these were integrated to capture a railway bridge. The lower deck lateral surfaces captured using TLS, while the upper dec...

Floor slab is one of the most important structure members in a building and largest consuming concrete. Conventional floor has been used for years disadvantages that can be improved with alternate methods. There lot alternative methods have construction world such as precast slab, half precast, hollow core many more. One bubble deck slab. The spherical reinforced concrete patented named Bubble ...
