This paper reports on theoretical, numerical and experimental research into the use of structural insulated panels as structural wall components. Methods to determine and improve the structural capacity of such panels are discussed. The results indicated the significant influence of load transfer through the panel core on structural behaviour. Symmetrical stiffening of both faces increased the bending stiffness of panels considerably, but hardly influenced load distribution. Creating asymmetrical sandwich panels had a large influence on the distribution of loads and therefore structural behaviour. The modelling included an analysis of panels connected to a sole plate at the bottom. The bottom connection was described as a fixed end in the theoretical model; this approach is validated by finite-element model results. Equations were then developed to determine the value of the deformation and stresses at any location in the structure. Owing to the influence of shear deformation, the bending moment transformed depending on the slenderness of the panel. This influenced the out-of-plane displacement as well as the stresses in the panel. This reaction can be explained by the fact that bending resulted in both bending deformation and shear deformation, and that the load distribution acted accordingly.

承重墙非对称高性能结构保温板的分析

本文报道了有关将结构隔热板用作结构墙构件的理论，数值和实验研究。讨论了确定和改善这种面板的结构能力的方法。结果表明，荷载通过面板核心传递对结构性能的重大影响。两个面的对称刚度大大提高了面板的弯曲刚度，但几乎不影响载荷分布。创建不对称的夹心板对载荷的分布有很大影响，因此对结构性能也有很大的影响。建模包括分析连接到底部底板的面板。在理论模型中，底部连接被描述为固定端。有限元模型结果验证了该方法的有效性。然后开发方程式，以确定结构中任何位置的变形和应力值。由于剪切变形的影响，弯矩根据面板的细长度而变化。这影响了平面外位移以及面板中的应力。这种反应可以通过以下事实来解释：弯曲导致弯曲变形和剪切变形，并且载荷分布相应地起作用。
