Timber–concrete composite structure is a type of efficient combination form composed of concrete floors and timber beams or floors through shear connectors, and shows good application potential in the floor system of timber buildings. The long-term performance of the timber–concrete composite structures is complex and is affected by the creep of timber and concrete, as well as the long-term slip of the shear connectors. This article presents a comprehensive overview of the research status on the long-term behavior of timber–concrete composite members and different shear connectors. For the shear connectors, the effects of loading levels, environments, and component materials on their creep coefficients are summarized. As to the timber–concrete composite members, both the experimental and numerical investigations are gathered into discussions: the connection types, component materials, loading conditions, and durations in the long-term tests are also discussed; various models for describing long-term behavior of timber, concrete, and connection systems are provided, and then a comprehensive description of the progress of numerical investigations over the last decades is made. In addition, the suggestions for future research are proposed to reach a clearer understanding of the bending mechanisms and mechanical characteristics of timber–concrete composite structures.

“…In absence of test data, Eurocode 5 provides values for slip modulus as a function of connection type, diameter, and weight of timber. Kser value for screws and dowel type fasteners is determined by equation (7) for SLS and equation (8) for ULS. Equations are for timber-to-timber joints, and slip modulus values must be doubled for TCC modeling [47].…”

Several studies have been made on timber concrete composite shear connectors and most of these connectors are brittle at failure. Ductile shear connectors are not studied as extensively as ordinary shear connectors and the interest to study high ductility shear connectors increased in the past two decades. Recent literature references were chosen and reviewed on construction techniques of timber concrete composite shear connectors. A detailed summary of timber concrete composites, the mechanical properties of connectors, and types of connection systems are presented. Experimentally validated design guides available for timber concrete composite systems are presented and the potential for the development of new simplified connectors is discussed. Finally, recent applications of timber concrete composite connectors and possible areas of future research regarding the development of high ductility and energy dissipation capacity shear connectors are stated.

“…A number of very different shear connectors for timber-concrete composite action systems have been developed and tested. Some of them are more oriented towards residential sector, but others are also successfully implemented in bridge construction, for further studies respective references are given in Fragiacomo, Lukaszewska (2011) and Bathon, Bletz-Muhldorfer (2010).…”

This paper presents results of the laboratory tests of timber-concrete structural connectors applicable (but not limited to) road/pedestrian bridges. The tested elements are discrete circular hollow section connectors installed in the pre-drilled slots of a glulam. Symmetrical push-out tests are conducted for two groups of connectors: 1) with wood core not removed; no interlayer between wood and concrete; 2) concrete in-fill core instead of the wood core; waterproofing membrane interlayer between concrete and timber elements. Main structural parameters of the connectors are established including ultimate shear capacity and slip modulus. Relationship between the connector’s stiffness and ultimate shear capacity is established and failure mechanisms are briefly discussed.
