钢结构稳定设计——理论与实践

Stability Design of Steel Structures-Theory and Practice

本文提出了实际工程结构的非线性理论设计和分析方法(NIDA),并以澳门回归纪念馆的设计为例,展示了本方法的优越性。在设计过程中,设计者无需假设K系数和有效长度,在结构分析完成后便可迅速完成设计,因此本文提出的方法既经济又便利。尽管对于钢框架在往复荷载及动力荷载作用下的弹塑性大位移分析已经非常成熟,但本文的方法开创了结构的非线性分析及设计的新纪元。

A non-linear integrated design and analysis (NIDA) method lor practical structures is proposed and applied to the Macao Return Memorial Hall. In the complete design approach, the effective length factor. K is not required to be assumed and the design is completed simultaneously with the analysis. The proposed technique is noted to be both economical and convenient to use. Although research on elasto-plastic large deflection analysis of steel frames under cyclic and dynamic loads has been successful, the codified application of a non-linear design analysis to practical design represents the beginning of an era for daily non-linear design of practical structures. It is hoped that codification of this non-linear analysis method in design will be carried out at an international collaborative level from which a massive global impact to the current design practice can be generated.
