Experimental investigation of timber-concrete composite beams subjected to long term loading is presented. The first type of experimentally tested timber-concrete composite beams consisting from the vertically nailed timber planks with concrete deck on the top. Shear connection between the concrete layer and timber members by grooves in timber was realized, which guarantee the composite action of two layers. The second type of the composite beams consists from separated vertically oriented timber planks in certain distance covered by OSB sheet and from fiber reinforced concrete layer on the top. Shear transfer between the timber planks and upper layers by the pair of steel screws spaced along the timber beams was realized. Three by three from both types of beams to four point bending tests was exposed. Experimental results with existing theoretical models are compared.
