BS ISO 11031:2016建立了计算地震荷载的一般方法，以用作 定义见ISO 8686系列，以及ISO 20332中定义的结构能力证明 以及ISO 4306中定义的起重机机械部件。本国际标准评估起重机在地震作用下的动态响应行为 作为起重机及其支撑结构动态特性函数的激励。该评估同时考虑了区域地震条件和局部地震的动态影响 起重机位置的地面条件。起重机的运行条件和地震损坏对起重机造成的风险如下 也考虑到了这一点。本国际标准仅限于正常使用极限状态（SLS），保持应力 在ISO 20332规定的弹性范围内。 本版本不适用于包括塑性变形在内的能力证明。什么时候 起重机供应商和客户之间的协议、其他标准或相关标准允许这些操作 可以使用考虑这些因素的文献。交叉引用:ISO 4306ISO 8686ISO 20332购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS ISO 11031:2016 establishes general methods for calculating seismic loads to be used as defined in the ISO 8686 series and for proof of competence as defined in ISO 20332, for the structure and mechanical components of cranes as defined in ISO 4306.This International Standard evaluates dynamic response behaviour of a crane subjected to seismic excitation as a function of the dynamic characteristics of the crane and of its supporting structure.The evaluation takes into account dynamic effects both of regional seismic conditions and of the local conditions on the surface of the ground at the crane location.The operational conditions of the crane and the risks resulting from seismic damage to the crane are also taken into account.This International Standard is restricted to the serviceability limit state (SLS), maintaining stresses within the elastic range in accordance with ISO 20332.The present edition does not extend to proofs of competence which include plastic deformations. When these are permitted by agreement between crane supplier and customer, other standards or relevant literature taking them into account can be used.Cross References:ISO 4306ISO 8686ISO 20332All current amendments available at time of purchase are included with the purchase of this document.
