木结构.穿孔金属板扣件和接头测试

[中文适用范围]： 本国际标准规定了用于确定承重木结构中冲孔金属板紧固件接头的强度和刚度的试验方法，具体如下：a）载荷-滑移特性和由嵌入突起的横向阻力引起的最大载荷，在施加力的方向和板的轴线（载荷-板角，oh）以及木材纹理方向（载荷-纹理角，9）之间的不同角度下； b) 板材在不同角度下的拉伸强度，w； c) 板材在不同角度下的抗压强度，a（可选试验）； d) 板材在不同角度下的剪切强度，%w。该国际标准与 ISO 6891 相关，后者给出了一般测试要求。此外，附录A还规定了交替弯曲试验钉根的方法。 [外文原描述]： ISO 8969:2011 specifies test methods for determining the strength and stiffness of joints made with punched metal plate fasteners in load-bearing timber structures, as follows: load-slip characteristics and maximum load resulting from the lateral resistance of the embedded projections, at various angles between the direction of the applied force and the axis of the plate (load-plate angle, α ), the direction of the grain of the timber (load-grain angle, θ ); the tensile strength of the plate at various angles, α ; the compression strength of the plate at various angles, α (optional test); the shear strength of the plate at various angles, α . ISO 8969:2011 is linked to ISO 6891, which gives general test requirements. In addition, a method for testing the nail root in alternate bending is specified in Annex A.
