Long-span timber floor elements increase the flexibility of a building and exhibit a significant market potential. Timber floor elements are endeavouring to fulfil this potential, but building projects employing long-span timber floors have encountered drawbacks. High costs and vibration performance are challenging, and the timber industry is under substantial pressure to find attractive solutions for building components with otherwise favourable environmental features. Only a few existing studies have investigated serviceability sensitivity in relation to timber floor connections. Interconnections are inexpensive to produce and install and may offer a resource-efficient approach to improving serviceability performance. In the present study, the effect of interconnections is investigated in a full-scale structural test. Floor elements positioned in different configurations have been tested for static and dynamic performance using different types of interconnections. The observed effects of interconnection types vary according to the configuration and direction of mode shapes, and are assessed in terms of shift in frequency, damping and resonant energy. These can all be utilised in combination with observed differences in the deflection parameter. The present work demonstrates that connections between timber elements have significant effects on timber floor serviceability and may offer interesting solutions to improve the vibration performance of long-span timber floors.

木材地板元件之间的互连的影响:结构规模测试的动态和静态评估

大跨度的木地板元件增加了建筑物的灵活性,并显示出巨大的市场潜力。木地板构件正在努力实现这一潜力,但是使用大跨度木地板的建筑项目遇到了缺点。高成本和振动性能具有挑战性,木材行业正面临巨大压力,要求为具有其他有利环境特征的建筑部件寻找有吸引力的解决方案。只有很少的现有研究调查了与木地板连接有关的适用性敏感性。互连的生产和安装成本低廉,并且可以提供一种资源有效的方法来改善可维护性性能。在本研究中,在全面的结构测试中研究了互连的影响。放置在不同配置中的地板元件已使用不同类型的互连进行了静态和动态性能测试。观察到的互连类型的影响根据模式形状的配置和方向而变化,并根据频率,阻尼和谐振能量的变化进行评估。这些都可以与偏转参数中观察到的差异一起使用。目前的工作表明,木材元件之间的连接对木材地板的使用寿命具有重要影响,并且可能会提供有趣的解决方案来改善大跨度木材地板的振动性能。观察到的互连类型的影响根据模式形状的配置和方向而变化,并根据频率,阻尼和谐振能量的变化进行评估。这些都可以与偏转参数中观察到的差异一起使用。目前的工作表明,木材元件之间的连接对木材地板的使用寿命具有重要影响,并且可能会提供有趣的解决方案来改善大跨度木材地板的振动性能。观察到的互连类型的影响根据模式形状的配置和方向而变化,并根据频率,阻尼和谐振能量的变化进行评估。这些都可以与偏转参数中观察到的差异一起使用。目前的工作表明,木材元件之间的连接对木材地板的使用寿命具有重要影响,并且可能会提供有趣的解决方案来改善大跨度木材地板的振动性能。
