【 摘 要 】

The subject of this paper is a new knowledge in experimental and numerical analysis of the stability of the wall panels with one-side board sheathing. The reinforcement of the panel is provided by means of glued timber composite I-shaped element consisting of a web made of a wood-based desk-OSB board embedded into flanges of solid timber. At present, the design of wall panels with I-shaped cross-section stiffeners and double-sided sheathing is based on test results and simplified analytical calculation. For the design of wall panels with I-shaped cross-section stiffener rib and one-sided board sheathing, a reliable procedure for determining the buckling load bearing capacity has not been described so far. It is assumed that the base of this work can be used for more effective material use of subtle light timber frames. By optimization of the supporting structure, increased heat-technical properties will be effectively achieved. New outputs of experimental analysis on wall panels in real dimensions, as well as material tests of individual components such as solid wood, OSB board and staples will be presented in this paper. Moreover, this paper presents the results of detailed numerical analysis, which are validated on the basis of the experiments performed.
