In the past decades, many novel shear connectors for implementation in steel-concrete composite beams have been investigated. In this paper, a demountable shear connection between a structural steel beam and a solid concrete deck, consisting of bolts and welded headed studs, is analysed. This system features the indirect shear force transfer through the additional element, a steel plate that is placed between a concrete deck and a top flange. Following the experimental results of previously conducted push-out tests, a numerical model has been developed. The model is used for a detailed analysis of the system behaviour as well as for the parametric study. Influence of a bolt diameter and a bolt hole diameter on shear behaviour of the connection has been discussed.
Prethodnih decenija intenzivno su ispitivana nova rešenja spojnih sredstava u smičućim spojevima spregnutih greda od čelika i betona. U ovom radu analiziran je montažno-demontažni podužni smičući spoj konstrukcionog čelika i pune armiranobetonske ploče, ostvaren pomoću zavrtnjeva i elastičnih moždanika s glavom. Ovakav spoj odlikuje se indirektnim prenosom sile smicanja kroz dodatni element, čelični lim, između betonske ploče i gornje nožice grede. Formiran je numerički model testa smicanja prema dostupnim prethodnim eksperimentalnim ispitivanjima. Model je iskorišćen za detaljnu analizu ponašanja podužnog smičućeg spoja, kao i za parametarsku analizu. Ispitivan je uticaj prečnika zavrtnja i prečnika rupe na ponašanje spoja pri smičućem opterećenju.
