摘要

This standard states Approval criteria for rigid seismic sway brace components and asseblies for pipe, tubing and conduit.For rigid seismic sway braces, the general requirements for seismic sway bracing components apply to the components that are attached to the structural element and the components that are attached to the pipe, tube or conduit. Although used in testing, the brace member that is attached between the building-attached component and the piping-attached component is used in testing, but not included within the scope of the standard.The evaluation of building-attached components is based on the premise that the component would either break, or deform in excess of the allowed limits, prior to either the failure of the attachment fastener, or the deflection of the structural member (e.g. beam). Therefore, the attachment fastener and structural members are not considered to be within the scope of this Approval Standard.The evaluation of piping-attached components is based on the premise that the component would break, deform in excess of allowed limits, or lose its grip on the pipe.Seismic sway brace components are designed to attach to pipe, tubing or conduit from Nominal Pipe Size (NPS) 1 to 12 inch (DN 25-300). 本标准规定了管道、油管和导管用刚性抗震斜撑组件和组件的批准标准。对于刚性抗震摇摆支撑，抗震摇摆支撑组件的一般要求适用于连接到结构元件的组件以及连接到管道、管或导管的组件。尽管在测试中使用了支撑构件，但连接在建筑物连接构件和管道连接构件之间的支撑构件用于测试，但不包括在本标准的范围内。建筑附属构件的评估基于以下前提:在附属紧固件失效或结构构件（如梁）变形之前，构件会断裂或变形超过允许的极限。因此，附件紧固件和结构件不在本认证标准的范围内。管道连接部件的评估基于以下前提:部件会断裂、变形超过允许的限制或失去对管道的抓地力。抗震摇摆支撑部件设计用于连接标称管道尺寸（NPS）为1至12英寸（DN 25-300）的管道、油管或导管。展开▼
