“…The measured values for the G1 test samples were taken from Premrov, M., Dobrila, P., Bedenik, B.S. [6] and additional new test samples from this research. Forces (F cr ) and (F u ) depend on fasteners disposition.…”

“…The main assumptions do not exactly coincide with the real state of FPB, in which the tensile strength is evidently lower than the compressive strength. Consequently, cracks in a tensile zone usually appear under heavy horizontal loads before stresses on the fasteners reach their yielding point, and the fibreboards usually do not behave as rigid elements [6] . However, using FPB as a coating material, a horizontal load shifts a part of the force over the mechanical fasteners to the fibreboard and the wall acts like a deep beam [1] .…”

“…In Dobrila and Premrov [6] experimental results using additional FPB were presented. The test samples with constant distance of s = 75 mm between the staples demonstrated higher elasticity, whilst bearing capacity and especially ductility were not improved in the desired range.…”

“…The test samples with constant distance of s = 75 mm between the staples demonstrated higher elasticity, whilst bearing capacity and especially ductility were not improved in the desired range. In the second solution, using diagonal steel strips [6] , it is evident from the relationship between the measured forces forming the first crack that the inserted steel diagonals are not very important. But the proportion between the measured crushing forces shows that the resistance of the reinforced panel's increases by 77% and ductility is improved by 39%.…”

This paper provides experimental analysis of timber-framed walls, coated with double fibreplaster coating boards fastened to the timber frame. As the walls under a horizontal load actually behave like a deep composite beam, the fasteners disposition is very important and directly influences bearing capacity and stiffness of the wall. Therefore, three different groups of test samples with staple distances of s = 37.5, 75 and 150 mm were experimentally analysed and compared. For groups G2 and G3 the failure of FPB occurred. It has been shown that proposed simplified Eurocode 5 methods, applicable for wood-based sheathing board might be unsuitable for the problems presented.

This paper provides an experimental analysis of timber-framed walls, coated with carbon fibre-reinforced polymers (CFRP) strengthened fibre-plaster boards, usually used as main bearing capacity elements in the construction of prefabricated timber structures. The tensile strength of the boards is lower than the compressive one and essentially lower than the strength of the timber frame, therefore it is convenient to strengthen boards in their tensile diagonal direction with high-strength materials in order to gain a higher capacity. It has been shown 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 connected to the timber frame. On the other hand, the ductility itself was not significantly improved. The test samples proved an important distinction in behaviour in timber frame-fibreboard connecting area, dependant on the boundary conditions between inserted CFRP strips and timber frame.
