A new diagnostic device for in-situ determination of conventional strength and modulus of deformability in compression of wood parallel to fiber
Original language description
The article presents a conception and prototype of a new diagnostic tool for in-situ evaluation of wood inbuilt into constructions. Current techniques and tools for structural assessment miss the solution that enables measuring of mechanical properties of wood with help of semi-destructive approach that focuses on longitudinal wood properties in a pre-drilled hole. The proposed device uses the principle of pushing jaws (?mini compression test) apart from each other in drilled hole of 12mm diameter to get as close as possible to pure compression loading mode in a laboratory. The measurement can be carried out in arbitrary depth in a wooden beam. The output from the device is the conventional strength and the modulus of deformability in compression (MODL) parallel to fiber direction. The principle implemented in the new device was tested both ways the experimental and numerical based finite element analysis. Numerical analyses based on probabilistic approach were performed in ANSYS compu
