“…Kong et al [89] reinforced the glulam with the upper concrete slab and bottom carbon fiber-reinforced polymer rebar (CFRP). After over 1-year-loading, the deflection of the glulam specimen and the hybrid one, which were loaded in indoor conditions, increased by 0.2 and 0.4, respectively.…”

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 this respect, concrete beam structures [5,6,[10][11][12][13]19,20,[29][30][31][32][33], as well as columns [8,34,35] and slabs [9,36] have mainly been examined. In addition, analytical [12,29,33,36] and numerical [6,11,19,20,30,32] models of elements containing UHPC or UHPFRC have been verified or validated, the properties of this material have been tested for use in repairs [14,37], and the possibilities of the modern monitoring of the structural elements which contain it have been tested [12]. It is worth mentioning here that there are also papers in which UHPC or UHPFRC is used as a component of composite beams where it is combined with glued-laminated timber [32,33] or fibre-reinforced polymer [31].…”

Experimental Research on Concrete Beams Reinforced with High Ductility Steel Bars and Strengthened with a Reactive Powder Concrete Layer in the Compression Zone

The article describes four-point bending tests of three reinforced concrete beams with identical cross-sections, spans, and high-ductility steel reinforcement systems. Two beams were strengthened in the compressed section with a thin layer of reactive powder concrete (RPC) bonded with evenly spaced stirrups. Their remaining sections, and the third reference beam, were made of ordinary concrete. Measurements of their deflections, strains and axis curvature; ultrasonic tests; and a photogrammetric analysis of the beams are the main results of the study. For one of the beams with the RPC, the load was increased in one stage. For the two remaining beams, the load was applied in four stages, increasing the maximum load from stage to stage in order to allow the analysis of the damage evolution before reaching the bending resistance. The most important effect observed was the stable behaviour of the strengthened beams in the post-critical state, as opposed to the reference beam, which had about two to three times less energy-absorbing capacity in this range. Moreover, thanks to the use of the RPC layer, the process of concrete cover delamination in the compression zone was significantly reduced, the high ductility of the rebars was fully utilized during the formation of plastic hinges, and the bending capacity was increased by approximately 12%.

“…The mechanical behaviour, CME and CMC of timber in radial and tangential directions are significantly different, but in large structural timber members, the radial and tangential directions are treated as one direction, namely perpendicular to grain direction. Moreover, the effect of temperature on swelling/shrinkage behaviour of timber has not been adequately investigated and constant shrinkage/swelling parameters have been typically adopted to predict long-term behaviour of timber structures in variable environmental conditions [14][15][16][17][18][19][20][21]. The accurate evaluation of CMEs and CMCs at different temperatures is also crucial in the investigation of moisture-induced stress in wood-based structural elements [9,22].…”
