随着钢筋混凝土和预应力混凝土结构的发展,国外一些主要国家在基本理论和设计方法方面进行了多方面的系统研究,取得了不少重大的进展。据不完全统计,仅美国钢筋混凝土学会组织的专门问题委员会就达110个以上,所研究的内容包括各种材料与结构的基本理论,设计方法,施工工艺与质量控制,一直到规范、手册,涉及的范围相当广泛。现仅根据一些不完整的资料,对钢筋混凝土设计方法和基本理论研究方面的若干发展概况作一简要叙述。
With the development of reinforced concrete and prestressed concrete structures, a number of major countries in the world have conducted systematic research on basic theories and design methods, and have made significant progress. According to incomplete statistics, there are more than 110 special issues committees organized by the American Society of Reinforced Concrete. The contents of the study include basic theories, design methods, construction processes and quality control of various materials and structures, and up to specifications and manuals. The scope involved is quite extensive. Based on some incomplete data, a brief description of the development of reinforced concrete design methods and basic theory is given.
