ISO 16670:2003旨在提供一种循环试验方法，作为推导木结构抗震设计所需参数的基础。该方法包括开发包络曲线（主干或骨架曲线，第A.5条给出了一个示例）的程序对于承受循环位移计划的接缝，该计划产生地震对接缝施加的代表性要求。它不包括国家标准或建筑规范中有时规定的参数标准。 ISO 16670:2003适用于承受横向荷载的接头，不适用于承受拔出力的接头。 ISO 16670:2003适用于在地震作用下加载的木结构中使用的机械紧固件制成的接头。

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.
