“…In the open literature, there are limited studies reporting the performance of flexure-critical concrete beams reinforced with Glass FRP (GFRP) bars under impact loads [33][34][35][36][37]. The test results showed that the beams experienced an average 15% enhancement of moment capacities under impact loads (with the drop mass 110 kg and height 1.2 m) as compared to that under static loads [33].…”

“…Moreover, extensive research has explored detailed experimental, numerical, and analytical methods to investigate the dynamic response of fiber-reinforced-concrete (FRC) beams [ 1 , 16 , 33 , 34 , 35 , 36 , 37 , 38 ]. For instance, considerable attention has been devoted to investigating the performance of concrete beams reinforced with Glass FRP (GFRP) bars, particularly under impact loading conditions [ 39 , 40 , 41 ]. The results indicated that these beams exhibited an average 15% increase in moment capacity under impact loading (using a drop mass of 110 kg at a height of 1.2 m) compared to static loading conditions.…”

With the growing use of steel-fiber-reinforced-concrete (SFRC) beams in environmentally friendly and rapid construction, it is essential to assess their impact performance. These beams may encounter unexpected impact loadings from accidents or terrorist attacks during service life. This study explored the impact of steel fiber content and drop hammer height on the impact load testing of corrosion-treated SFRC beams. Experiments were conducted with varying steel fiber contents (0%, 0.25%, 0.5%, 0.75%, and 1.0%), and drop hammer height (1 m, 2 m, and 3 m). The corrosion test demonstrates that SFRC beams supplemented with steel fibers showcase a diminished surface rust spot area in comparison to those lacking fibers. This improvement is ascribed to the bonding between fibers and the concrete matrix, along with their current-sharing properties. SFRC beams, subjected to impact testing, exhibit concrete crushing at the top without spalling, showcasing improved impact resistance due to increased fiber content, which reduces crack formation. Additionally, different fiber contents yield varied responses to impact loads, with higher fiber content notably enhancing overall beam performance and energy dissipation capacity. Energy dissipation analysis shows a moderate increase with higher fiber contents, and impulse impact force generally rises with fiber content, indicating improved impact resistance.

“…The following types of activities have been performed [2][3][4][5][6][7][8] during the highway overpass survey: • familiarization with the project documentation in terms of construction solution adopted in the project and as-built documents for construction; • control measurements of the bridge supporting foundations are taken in the form of load distribution structures, supported by drilled piers with a diameter of 1500 mm. The abutment foundations are also taken in the form of load distribution structures, supported by drilled piers of a diameter of 1500 mm.…”

The article presents results of the overpass condition survey, technical survey, static tests and assessment of the structure operational reliability, a doubledecker overpass on Almaty-Kapshagai highway section in Kazakhstan. Technical survey determined the dimensions of the overpass, the camber of reinforced concrete superstructures main beams and checked the values of the overpass roadway actual transverse and longitudinal slopes. The calculation and analytical assessment of the overpass load-bearing structures, for the strength of the bending moment, are performed. Static tests of the overpass split beam superstructure of a length of 33.0m were conducted. Trucks loaded with ballast were accepted as a test load.
