  • Experimental and numerical analysis of prefabricated timber-framed walls strengthened with CFRP strips
    Premrov, Miroslav, 1967- ; Dobrila, Peter ; Špacapan, Igor, 1946-
    This paper provides an experimental and numerical analysis of timber-framed walls coated with carbon fibre-reinforced polymers (CFRP) strengthened fibre-plaster boards. The elements are usually used ... as main bearing capacity elements in the construction of prefabricated multi-level timber residential buildings. Because the tensile strength of the fibre-plaster boards is approximately 10-times lower than the compressive one, it is convenient to strengthen the boards in their tensile diagonal direction with CFRP strips, which are glued to the boards. It has been shown by experiments that the inclusion of CFRP diagonal strip reinforcement on the load- carrying capacity can be quite high and that it is maximized when the carbon strips are additionally connected to the timber frame. Based on analysis of experimental research results [1] special approximate mathematical models have been developed. The models enable simultaneously to consider the influence ofinserted CFRP strips, flexibility of mechanical fasteners in the connecting areas and any appearing of tensile cracks in the coating boards.
