“…Additionally, the analysis could indicate whether enough connectors are used for the layered structure to remain intact. Additionally, the ratio of shear stress and slippage provides a characteristic called the interface slip modulus, which is the main characteristic defining interface stiffness [29]. The shape of the curve itself is an indicator of whether the deterioration of the interface would be sudden and uncontrollable or slower and less dangerous.…”

The behaviour of the interface between two concrete layers, subjected to shear, is a complex process that is influenced by many different parameters. Knowledge of concrete interface performance is insufficient to this day. Most of the existing analytical methods are only suitable for determining the highest interface shear resistance and do not consider the interface behaviour at other stages. This article focuses on smooth concrete interfaces, which have their layers cast at different times (cold-joint interface). By analysing the results of different experimental push-off tests, presented in the literature, a novel analytical method was developed for the previously described concrete interface. Furthermore, numerical models of push-off tests were developed. A parametric numerical analysis was employed to determine the influence of various physical parameters that might affect interface shear behaviour. Most importantly, the results acquired using the proposed analytical method were compared with the findings of numerical analysis and experimental results acquired by other authors. The values of shear stress and slippage were found to be relatively close. Therefore, the proposed analytical method is suitable for the analysis of smooth concrete interfaces cast at different times.

Kompozitni konstrukcijski sistemi podrazumevaju racionalno spajanje elemenata od odgovarajućih materijala, tako da se optimalno iskoriste njihova svojstva. Spregnute konstrukcije imaju najširu primenu u inženjerskim konstrukcijama velikog raspona [12], ali mogu se uspešno primeniti i u stambenim i poslovnim objektima. Adekvatnim spajanjem konstrukcijskih elemenata istih ili različitih fizičko-mehaničkih karakteristika u integralni poprečni presek, postiže se osnovni cilj postupka, tj. povećava se nosivost sistema u odnosu na pojedinačne elemente. U zavisnosti od primenjenih materijala, spregnute konstrukcije koje se često primenjuju u građevinarstvu uglavnom su tipa drvo-drvo, beton-beton, čelik-beton i drvo-beton. Budući da su spregnute konstrukcije-napravljene od različitih materijala i različitim načinima spajanjadostigle veoma visok stepen primene u građevinarstvu u poslednjih nekoliko decenija, neophodna je njihova preciznija analiza, kao i preciznije projektovanje. Poznato je da upotrebljeni tip sredstava za sprezanje najviše utiče na globalno ponašanje spregnutih konstrukcija. Stoga, od ključnog značaja je to kako da se uvede problem ponašanja veze između spregnutih materijala u analizi i proračunu.
