e repair and strengthening of reinforced concrete members are very important due to several factors, including unexpected increases in load levels and/or the damaging impact of aggressive environmental conditions on structural concrete members. Many researchers have turned to using materials for the repair and strengthening of damaged structures or the construction of new concrete structural members. Ultrahigh-performance fibre-reinforced concrete (UHPFRC), characterized by superior structural and durability performance in aggressive environmental conditions, is one of the materials that have been considered for the repair and strengthening of concrete structural members. e repair or strengthening of concrete structures using UHPFRC needs a thorough knowledge of the behaviour of both the strengthening material and the strengthened concrete structure at service load conditions, in addition to an understanding of the design guidelines governing the use of such materials for effective repair and strengthening. In this study, the recent issues and findings regarding the use of UHPFRC as a repair or strengthening material for concrete structural members are reviewed, analysed, and discussed. In addition, recommendations were made concerning areas where future attention and research on the use of UHPFRC as a strengthening material needs to be focused if the material is to be applied in practice.

“…Novi pristup u armiranju betona razvijen je 2008. godine, a ispitivanja su pokazala da se armiranjem betona u različitim slojevima s različitim vlaknima u gredama i pločama postiže bolja otpornost na savijanje pod utjecajem jednolikog opterećenja [8]. Iskhakov i suradnici ispitivali su inovativni materijal kao zamjenu prilikom popravaka betonskih konstrukcija [9]. Upotrijebili su dvije vrste materijala u gredi, a obični beton i beton visokih uporabnih svojstava ugrađeni su na donji i gornji sloj grede.…”

“…Upotrijebili su dvije vrste materijala u gredi, a obični beton i beton visokih uporabnih svojstava ugrađeni su na donji i gornji sloj grede. Cilj je tog istraživanja bio postići optimalnu količinu vlakana s najvećim Poissonovim koeficijentom i žilavosti elemenata [9]. Njihovi eksperimentalni rezultati pokazuju da debljina sloja treba biti ista kao i debljina tlačne zone grede [9].…”

“…S obzirom na to, ovo je istraživanje provedeno kako bi se ispitala žilavost slojevito armiranih greda izloženih cikličkom opterećenju, a zaključeno je sljedeće: 3. Ovo istraživanje potvrđuje prethodne spoznaje koje se odnose na količinu vlakana, vrstu vlakana te poziciju betonskih slojeva s obzirom na dobivene rezultate ispitivanja mikroarmiranog betona [9][10][11][12][13]. 4.…”

Tehničko sveučilište Babol NoshirvaniStrojarski fakultet rabiee@nit.ac.ir Autori:Izvorni znanstveni rad Maysam Ghasemi Naghibdehi, Morteza Naghipour, Mahmood Rabiee Ponašanje slojevito mikroarmiranih betonskih greda izloženih cikličkom opterećenju Tijekom zadnjih deset godina primjenjuje se slojevito mikroarmiranje kao nova metoda za proizvodnju armiranobetonskih elemenata. U radu su prikazani rezultati ispitivanja svojstava slojevito mikroarmiranih betonskih greda izloženih djelovanju cikličnog opterećenja. Za pripremu uzoraka primijenjena su čelična i polipropilenska vlakna. Betonske grede s potpunim kompozitnim djelovanjem ojačane su sa 0,5 do 2 % čeličnih vlakana, a slojevito mikroarmnirane grede sadrže 1,3 % čeličnih vlakana. Dobiveni rezultati pokazuju da se primjenom slojevitog mikroarmiranja betona povećava disipacija energije uslijed cikličkog opterećenja. Behaviour of functionally graded reinforced-concrete beams under cyclic loading Over the past decade, the functional grading has been applied as a new method for the manufacturing of reinforced-concrete elements. The objective of this investigation is to evaluate performance of the functionally graded reinforcedconcrete beams exposed to cyclic loading. The steel and polypropylene fibres are used for the preparation of samples. Concrete beams with full composite action are strengthened with 0.5 to 2 % of steel fibres, and functionally graded RC beams contain 1.3 % of steel fibres. The use of the functionally graded method to reinforce concrete increases the dissipated energy due to the applied cyclic loading.
