摘　　要：采用钉连接工字梁翼缘与覆板,研究钉直径、覆板种类和厚度对钉连接节点处静态和动态承载性能的影响。结果表明,对于两种覆板材料,随着覆板厚度和钉直径的增大,连接节点处的静态承载和动态承载性能基本呈现增加的趋势;采用直径3.8 mm的圆钉,进行22 mm厚定向刨花板(OSB)与工字梁翼缘连接时,试样具有较佳的静态和动态承载性能。实际生产过程中,需根据覆板的厚度选择不同直径的圆钉。In order to make an I-beam for tests,LVL,as flange materials,and two kinds of structural panels,as sheathing materials,were connected by nails with different diameters.Thereafter,static and dynamic bearing capacity of the connections was tested.Testing results showed that the static and dynamic bearing capacity of the connections increased with increasing sheathing thickness and nail diameter.It was observed that when nail diameter was 3.8 mm,to connect 22 mm thick oriented strand board(OSB),the connection possessed better performance.It was concluded that selection of nail diameters for making this kind of I-beam should consider sheathing thickness in practice.
