起重机 抗震设计原理

[中文适用范围]： 、设计参数的选取、结构分析的方法以及抗震措施的实施要求。内容适用于各类起重设备的抗震设计和评估，为相关行业提供了统一的技术规范和指导。 ***此介绍可能不准确，请注意参考原文。 [外文原描述]： 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. ISO 11031:2016 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. It is restricted to the serviceability limit state (SLS), maintaining stresses within the elastic range in accordance with ISO 20332. It 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.
