ISO 4866:2010建立了关于评估结构振动影响的振动测量和处理数据的原则。它不包括激励源,除非激励源指示动态范围、频率或其他相关参数。结构振动影响的评估主要是通过结构的响应,使用适当的分析方法来确定频率、持续时间和振幅。ISO 4866:2010仅涉及结构振动的测量,不包括气载声压和其他压力波动的测量,尽管考虑了对此类激励的响应。
ISO 4866:2010适用于所有建在地面或地下的结构。使用或维护此类结构,包括建筑物、具有考古和历史价值的结构(文化遗产)、桥梁和隧道、气体和液体装置,包括管道、土结构(e。
g、 堤坝和堤岸),以及固定的海上设施(如码头和码头)。
ISO 4866:2010不适用于某些特殊结构,包括核电站和大坝。
结构的响应取决于激励。ISO 4866:2010检查了受激励源影响的测量方法,即任何源(如地震、飓风、爆炸、风荷载、空气噪声、音爆、内部机械、交通和施工活动)诱发的频率、持续时间和振幅。
ISO 4866:2010 establishes principles for carrying out vibration measurement and processing data with regard to evaluating vibration effects on structures. It does not cover the source of excitation except when the source dictates dynamic range, frequency or other relevant parameters. The evaluation of the effects of structural vibration is primarily obtained from the response of the structure, using appropriate analytical methods by which the frequency, duration and amplitude can be defined. ISO 4866:2010 only deals with the measurement of structural vibration and excludes the measurement of airborne sound pressure and other pressure fluctuations, although response to such excitations is taken into consideration.
ISO 4866:2010 applies to all structures built above or below ground. Such structures are used or maintained and include buildings, structures of archaeological and historical value (cultural heritage), bridges and tunnels, gas and liquid installations including pipelines, earth structures (e.g. dykes and embankments), and fixed marine installations (e.g. quays and wharfs).
ISO 4866:2010 does not apply to some special structures, including nuclear plants and dams.
The response of structures depends upon the excitation. ISO 4866:2010 examines the methods of measurement as affected by the source of excitation, i.e. frequency, duration, and amplitude as induced by any source (e.g. earthquake, hurricane, explosion, wind loading, airborne noise, sonic boom, internal machinery, traffic, and construction activities).
