本节主要讲授与钢结构技术发展水平、市场前景和设计原理相关的专业英语词汇和表达。

    (1) 钢结构的技术发展水平和市场前景 (State-of-the-art & prospective market)

从Technology(技术)、Economy (经济)和Enviroment (环境)三个角度分析。

    (2) 钢结构设计原理 (Design rationale of steel structures) 

    为满足Safety(安全性)、Serviceability(适用性)和Durability(耐久性)三个功能要求，钢结构或构件需要进行Strength (强度)、Stability(稳定)和Rigidity(刚度)的计算。
