木结构.机械紧固件接头.准静态逆循环试验方法

[中文适用范围]： 本国际标准旨在提供一种循环试验方法，作为木结构抗震设计所需参数推导的基础。 该方法包括为受循环位移表影响的关节开发包络曲线（骨干或骨架曲线；第 A.5 条中给出的示例）的程序，该循环位移表产生地震对关节施加的代表性要求。 它不包括有时在国家标准或建筑规范中规定的参数标准。 本标准适用于承受横向载荷的接头，不适用于承受拔拔力的接头。 本国际标准适用于承受地震作用的木结构中使用的机械紧固件接头。 注 1：在本标准的上下文中，术语“接头”在当今的北美英语中意为“连接”。 注2：公认的是，对于某些特殊类型的接头，如果实现了本节中的试验目标和第6章中的原则，则可能需要修改试验方法。 详细信息请参见第 A.2 条。 [外文原描述]： ISO 16670:2003 is intended to provide a cyclic test method as a basis for the derivation of parameters which are required in seismic design of timber structures. The method includes procedures to develop the envelope curves (backbone or skeleton curves, an example is given in Clause A.5.) for joints subjected to a cyclic displacement schedule which produces representative demands imposed on the joints by earthquakes. It does not include criteria for parameters which are, at times, stipulated in national standards or building codes. ISO 16670:2003 is intended for joints subjected to lateral load and is not applicable to joints subjected to withdrawal forces. ISO 16670:2003 is applicable to joints made with mechanical fasteners used in timber structures loaded under seismic action.
