500MPa级钢筋混凝土结构的研究进展

摘要

The 500 MPa fine grains steel bars in concrete components can obviously reduce the total steel quantity,significantly improve the engineering quality and achieve good social and economic benefits.This paper presents an analytical discussion on the current research and findings about the reinforced concrete structures with 500 MPa fine grained steel bars at home and abroad,summarizes the different tests of the domestic reinforced concrete structures with 500 MPa fine grained steel bars and expounds the different major research results of the different components of the reinforced concrete structures with 500 MPa fine grained steel bars of fine grains.In addition,the suggestions are offered for further research in the paper.%在混凝土构件中使用500MPa级高强度钢筋可以明显地减少用钢量,显著提高工程质量,并能取得较好的社会经济效益.介绍了当前500MPa级钢筋混凝土结构的国内外研究现状,总结了国内500MPa级钢筋混凝土不同构件的试验,对500MPa级钢筋混凝土不同构件的主要试验研究成果作了阐述.同时对未来500MPa级钢筋混凝土结构的研究提出了建议.
