使用性能较差的木地板可以通过混凝土面层进行升级，形成木-混凝土复合材料。升级使地板变硬，减少了对动态激励的振动响应的感知。尽管木材-混凝土复合材料近年来成为一个既定的研究领域，但人们对这些地板类型的振动响应知之甚少。本文探讨了用混凝土面层升级时木地板的振动响应如何变化，特别关注振动的基频。分析模型利用欧洲规范 5 (EN 1995-1-1) 的伽玛方法，用于预测添加顶部后振动基频如何变化。该模型在用于进行参数研究以确定共同因素的影响之前，会与木材混凝土板的实验测试进行比较。研究发现，面层和木地板之间的高度相互作用，识别...
Timber floors suffering from poor serviceability performance can be upgraded with a concrete topping to form a timber–concrete composite. The upgrade stiffens the floor, reducing the perception of a vibration response to dynamic excitation. Despite timber–concrete composites becoming an established research area in recent years, relatively little is known about the vibration response of these floor types. This paper explores how the vibration response of a timber floor changes when upgraded with a concrete topping, with particular attention given to the fundamental frequency of vibration. An analytical model, utilising the gamma method of Eurocode 5 (EN 1995-1-1), is used to predict how the fundamental frequency of vibration changes with the addition of a topping. The model is compared with experimental testing of timber–concrete panels before it is used to conduct a parametric study to establish the effect of common factors. It is found that high interaction between the topping and timber floor, identify...
