经过半个多世纪的工程实践与科学研究,钢筋混凝土结构的计算原理已经进入一个比较明显的新阶段。好些国家都在最近几年相继修订了各自的设计规范,纳入了新的计算原理。但另一方面,这些规范目前常以草案的形式颁布,说明其中有些问题仍处在有待深究的状态。在这种情况下,探讨一下钢筋混凝土结构计算原理方面的国外进展,无疑是有益的。 After more than half a century of engineering practice and scientific research, the calculation principle of reinforced concrete structures has entered a relatively obvious new stage. In recent years, many countries have revised their own design codes in succession and incorporated new calculation principles. However, on the other hand, these norms are currently promulgated in the form of drafts, indicating that some of these issues are still under investigation. Under such circumstances, it is undoubtedly beneficial to explore the foreign progress in the calculation principle of reinforced concrete structures.
