美石油规范API-2A 4.2.3 节点设计的句子含义 [复制链接]

API-2A的 4.2.3 定义了“最小承载力”有：The connection at the ends of tension and compression members should develop the strength required by design loads ，
but not less than 50% of the effective strength of the member.
问:
1)effective strength 是什么？
2）为何规定不小于50%的effective strength of the member.？

多谢讨论。

不是石油专业的，只是个翻译员，给点个人意见讨论：
有效强度
因为是在构件两端的连接，所以两端都大于50%时，在构件承受effective strength以上的负载时，才不会在连接处断裂。
是这样不

感觉你这个问题好像是有关钻柱设计的，建议看看钻井工程和材料力学

API-2A的 4.2.3 定义了“最小承载力”有：

The connection （连接点） at the ends of tension and compression members （位于拉伸和压缩构件端点的） should develop （应该达到） the strength required by design loads （设计载荷要求的强度），
but not less than 50% of the effective strength of the member. （但是不能小于构件有效载荷的 50%）



问:
1)effective strength 是什么？
2）为何规定不小于50%的effective strength of the member.？

多谢讨论。
