The behavior of sheet adjustment joints for repairing wooden historic structures
In addressing sheet joints, theoretical outcomes were first compared with experimental results. Then a number of calculations were performed with changing parameters, from which limits in forces which form in different parts of the sheet can be estimated. From the stated results, in full utilization of the linear load, it follows that neither the application of various fasteners nor their addition has any great influence on the load capacity of the joint. Solutions with an inserted sheet reduce the tension in the weakened section, increase the number of cuts to the pin, and therefore in terms of statics is a very suitable solution.
If the state of usability is decisive in design, it is then advisable to reduce the length of the sheet so in the end it is stressed the least. This measure increases the rigidity of the joint and thus the whole beam, but it is necessary to check the load capacity which decreases with reduction.
