轻型木结构用意杨结构胶合板集中静载性能试验研究

TEST FOR PERFORMANCE OF POPLAR RESIDUE PLYWOOD SHEATHING IN LIGHT WOOD FRAME CONSTRUCTION UNDER CONCENTRATED LOADS

介绍了轻型木结构楼、屋面板集中静载性能试验的条件、装置和方法,根据规范要求研制了加载装置,并进行了木结构用意杨结构胶合板的集中静载性能试验研究,旨在为国产速生林用于轻型木结构的研究提供一些试验数据。试验结果表明:与国外结构胶合板具有相同厚度的轻型木结构用意杨屋面板和楼面板,其集中载荷受弯性能均优于我国木结构工程施工质量验收规范标准要求。

Test equipment, conditions and methods for concentrated load performance testing for sheathing panels in light frame con- struction were introduced in this paper. The concentrated load performance of plantation grown Italian poplar plywood used as roof and flooring panels in light frame construction was also studied. The results showed that the performance of the Italian poplar plywood, with the same thickness as foreign plywood products, exceeded the requirements for the related standards.
