ABSTRACT
ABSTRACT: Analysis of shear composite connections is a part of extensive research of timber-concrete composite systems. In the first phase of the project, timber-concrete composite beams with a screwed composite connection were investigated. The next phase examined the composite deck system consisting of a vertically laminated nailed timber and concrete using a grooved connection. Finally, composite structural elements with a lightweight concrete and a timber deck system was realized using a special adhesive for wet concrete. In this paper three connection types with different connection stiffnesses are analyzed. To determine the shear parameters of the composite connections, short term shear tests were performed. An experimental estimation of mechanical parameters is presented and the results are finally compared and discussed.
