GB/T 30024-2013 in English

《GB/T 30024-2013起重机 金属结构能力验证》由TC227（全国起重机械标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准基于极限状态法规定了对起重机金属结构进行能力验证所确定的一般条件、要求、方法和参数值,以与ISO8686中载荷与载荷组合的适用部分协同使用。
本标准具有通用性,适用于所有类型的起重机。对于专用特殊的起重机,可由其他标准规定其能力验证的特定要求。
通过理论验证计算和/或测试进行能力验证,旨在以所建立的强度极限(如屈服极限、疲劳、脆性断
裂)来避免与结构性能相关的危险。
根据ISO8686-1,能力验证计算可以采用两种方法:分项载荷系数的极限状态法、整体安全系数的
许用应力法。允许用许用应力法替代本标准表述的极限状态法。
本标准不包括附属部件(如栏杆、楼梯、走道、司机室)的能力验证计算。但需考虑这些附属部件对主要结构产生的影响。
注:弹性稳定的能力验证另有国际标准规定。

Scope

This standard specifies the general conditions, requirements, methods and parameter values for proficiency testing of crane metal structures based on the limit state method, to be used in conjunction with the applicable part of ISO 8686 for loads and load combinations. This standard is general and applies to all types of cranes. For special and special cranes, other standards may specify the specific requirements for proficiency verification. Capability verification by means of theory-verified calculations and/or tests aimed at avoiding hazards associated with structural performance at established strength limits (e.g. yield limit, fatigue, brittle fracture). According to ISO 8686-1, two methods can be used for proficiency testing calculations: the limit state method of the sub-item load factor, and the allowable stress method of the overall safety factor. It is permissible to use the allowable stress method instead of the limit state method expressed in this standard. This standard does not include proficiency testing calculations for accessory components (such as railings, stairs, walkways, cabs). However, the impact of these auxiliary components on the main structure needs to be considered.
