Behaviour of a Timber-Concrete Composite Beam with Glued .

Summary. The paper reports the results of a collapse test performed on a 6 m span timber-concrete composite beam with glued re-bar connection. The beam was first ramp loaded to failure, then some push-out tests were performed on specimens cut from the end of the beam in order to fully characterise the connection

Glued Composite Timber-Concrete Beams. I: Interlayer Connection .

The composite interaction in timber-concrete beams is usually achieved with mechanical devices, such as shear connectors or plates driven into the materials. However, this connecting system shows some inherent inconveniences, such as the need for drillings and the limited mechanical improvement owing to interface..

Composite Timber Beams Strengthened by Steel and CFRP .

Composite timber beams strengthened by U -shape steel sections and carbon fiberreinforced plastic (CFRP) are studied experimentally in this paper. Specimens with various strengthening, i.e., steel only, CFRP only, and a combination of the two, were considered under three-point flexural tests. Failure, displacement and..

Composite Beams of Steel and Timber: Ingenta Connect

Composite steel-concrete buildings are commonplace, but they are incompatible with low-carbon construction technologies. This is because the manufacture of the cement used in the flooring slabs, which is cast in-situ around headed stud connectors, is associated with the production significant CO2 emissions, and..

Epoxy mortar timber beam upgrading: International Wood Products .

The physical and mechanical properties of brown-pigmented particulate composites based on epoxy polymer reinforced with quartz particles were assessed experimentally. The best setup condition was chosen to repair Maçaranduba and Cedrinho timber species. A full factorial design was conducted to evaluate the effect..

Bond stress system of composite concretetimber beams .

Composite beams require an adequate connection system. This paper describes composite concrete-timber beams with a bonded connection system employing prestressed steel connectors. The connection is obtained by means of threaded steel bars inserted into the holes of timber and prestressed by a normal force

Experimental study of timber-to-timber composite beam using .

This paper presents exploratory research related to novel full-scale multi-layered timber beams with composite action achieved with welded-through wood dowels. Different multi-layer beam designs, where the timber layers were interconnected with welded wood dowels providing interlayer shear resistance, were tested in..
