23rd International Conference on Modelling in Mechanics 2025 The significance of experimental testing in the static design of timber structures Pavel Dobeš* Centre for Building Experiments and Diagnostics, Faculty of Civil Engineering, VSB – Technical University of Ostrava Abstract The design of timber structures in most European countries is governed by the common standard Eurocode 5. The standard provides basic information on the design of partial elements, composite parts and also their connections, but it lacks some important knowledge, arising mainly from requirements of the scientific research, but also from the rapidly developing construction practice. Thus, experimental testing plays an important role in the verification of load-carrying timber structures. The aim of the paper is to present test results of selected timber structures and their comparison with standard approaches and numerical models within static design in practice. It deals with the determination and comparison of the horizontal load-carrying capacity and stiffness of wall panels in the system of a lightweight frame structure with OSB sheathing. Wall panels with different types of load-carrying sheathing were loaded with a horizontal force in order to monitor their deformation response to the load. The results of experimental tests were subsequently compared with analytical standard calculations and numerical models. Experimental tests demonstrated the suitability of using some sheathing methods in practice. Numerical models showed good agreement with measured data. © 2025 The Authors. Published by ELSEVIER B.V.
