摘要

本文的目的是对有和没有服务开口的交叉层压木地板的动态特性和弯曲刚度进行数值研究。对外层沿面板纵向取向的五层面板进行了分析。为了利用有限数量的测量和结构测试来探索这种地板系统的全部潜力，提出了基于有限元方法的模型，并根据实验结果进行了验证，然后用于研究地板开口位置对主要结构性能参数的影响。结果表明，当需要额外的服务开口时，如果开口在地板上的几何位置足够，交叉层压木地板的主要结构特征可以略有降低。

Finite Element Analysis of Dynamic Characteristics and Bending Stiffness for Cross Laminated Timber Floor Panels with and without Openings

The aim of this paper is to present numerical investigations of dynamic characteristics and bending stiffness for cross laminated timber floor panels with and without service openings. Five-layer panels with the outer layers oriented in the longitudinal direction of the panel have been analyzed. In order to explore the full potential of this floor system using a limited number of measurements and structural tests, models based on the finite element method have been proposed, validated against experimental results and then used to investigate the effect of opening position in the floor on main structural performance parameters. The results showed that, when the need for additional service opening appears, a slight decrease of the main structural characteristics of the cross laminated timber floor panels is achievable with an adequate geometrical position of the opening in the floor.
