横向受力钉木与混凝土连接的试验分析
摘 要
这项工作旨在评估欧洲规范5中提出的横向加载钉木-混凝土连接方法的准确性。首先，利用美国松的木材元素，分析和讨论了欧洲规范5提出的传力杆式紧固件方法的充分性。最初，在单剪和双剪销钉式连接的推出试验中，使用了方形和圆形光滑钉子。随后，在单剪、木材种类和试验程序中，使用相同类型的紧固件（钉子）对木材-混凝土连接进行了类似的研究。研究了永久模板的使用及其影响。其结果是，通过使用欧洲规范5提供的分析，当存在时，获得承载力和滑移模量的值之间的比较，并给出实验结果。

Experimental analysis of laterally loaded nailed timber-to-concrete connections
Abstract
This work intends to assess the accuracy of the methodology proposed in the Eurocode 5 for laterally loaded nailed timber-to-concrete connections. First, the adequacy of the methodology proposed by Eurocode 5 for the dowel-type fasteners is analyzed and discussed, using timber elements from Pinus pinaster Ait. Square and round smooth nails have been used, initially on push out tests of single and double shear dowel-type connections. Later, a similar investigation is carried out on timber–concrete connections, using the same kind of fasteners (nails), in single shear, wood species and experimental procedure. The use and the influence of permanent formwork are also investigated. As a result, comparisons between the values obtained for the load-carrying capacity and the slip modulus using the analysis provided by the Eurocode 5, when existing, and the experimental results are presented.
