结构用钢材

Through model test of new high- strength steel conical shell with ring frame ,and relevant analysis,it is shown in this paper that the failure of ring-framed conical shell can be traced to the neutral plane on longitudinal section where the structure strength is relatively weak.

通过新的高强度钢材环肋圆锥壳模型实验，及采用解析方法分析表明，环肋圆锥壳体破坏的原因是结构相对薄弱处纵剖面上的中面应力所致。并提出用"灰色系统"理论预测破坏载荷的计算方法，建议今后模型实验和现役潜艇的耐压船体寿命估算中可采用这种方

This seminar introduces methods for the structural analysis of historical monuments, including masonry, timber, iron, steel, and concrete structures. Short lectures will be followed by discussion sessions, together with weekly readings and a series of smaller assignments. Each student will write a final paper on a topic of their choosing. Final papers may be predominantly historical, with structural analysis to support the main arguments, or predominantly structural, with historical analysis to provide context.

概论该课程介绍了对历史丰碑上有名建筑的结构分析方法，涵盖了石材、木材、钢材、铁和混凝土结构等，课堂内以讨论的形式进行（结合每周的阅读和一系列小作业），每个学生自选主题写一篇论文作为期末论文，论文需用结构分析的方式去论证主要观点以体现显著的历史性，或者以历史分析的方式结合历史环境去表达其显著的结构特点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
