Composite timber beams strengthened by U -shape steel sections and carbon fiber reinforced 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
Summary. This paper presents the results of an experimental programme that includes the tests of six timber concrete composite beams and forty shear test specimens. The beams, 5.60 metres long, were made with glued laminated spruce beams with a top lightweight concrete layer. Steel screws that crossed the contact
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
LSL and OSL offer good fastener-holding strength and mechanical connector performance and are commonly used in a variety of applications, such as beams, headers, studs, rim boards, and millwork components. These products are members of the structural composite lumber (SCL) family of engineered wood products.

The topping slab is reinforced to make the composite floor system continuous over steel beam supports. The structural system is illustrated with Figures 1.3 and 1.4 on the following page. The steel beams have been designed to be asymmetrical in order to simplify the placement of the timber decks.

I've always maintained that the The engineer can specify a beam that will satisfy all applicable code criteria, and you'll sleep better knowing the beam is adequately sized. Regarding the use of
