摘要
某工程储罐顶盖采用了嵌入式毂节点形式的单层网壳结构,施工过程中,该网壳整体粉碎性坍塌.本文对该网壳结构的原设计进行评估,并对钢网壳无延性坍塌原因进行分析.该网壳的设计问题和事故原因具有典型的代表性,几乎涉及到规范规定的各个方面,从计算到设计,再到施工.本文对上述内容进行了全面分析.
Embeded hub joint singl shell collapsed totally in construct analyzes the reasons for the non- reasons for calculation, above. the accident design and are typica constructi e-layer steel shell is used as the roof of the oil tanks in some project. The ion. This article gives the appraisal of the original design of the shell and ductile collapse. The problems existing in the original design and the 1, which almost involve every part of the related Chinese code, including on. The article gives a detailed introduction of the content mentioned
