钢筋混凝土构件的尺寸效应研究进展及展望

Research Progress and Prospect of Size Effect on Reinforced Concrete Members

为提高大尺寸钢筋混凝土构件设计的合理性,对各国钢筋混凝土构件的尺寸效应研究现状进行了综述与分析,并重点介绍了混凝土强度、钢筋混凝土梁和钢筋混凝土柱的尺寸效应试验研究成果;在归纳总结的基础上,对钢筋混凝土构件尺寸效应研究的发展进行了展望,建议了进行涵盖大尺寸混凝土构件破坏试验的尺寸效应研究方案。

In order to improve the rationality of design of reinforced concrete （RC） members, the size effect covering large size of RC members at home and abroad should be considered. The stateof-the-art of studies on size effect of RC members was summarized and analyzed. The results of size effect experimental studies about concrete intensity, RC beam and RC column were introduced emphatically. Based on the summaries of previous research, the research progress and prospect of size effect on RC members was introduced. Finally, a research plan of size effect covering large size of concrete members destruction tests was suggested.
