1·The corrosion of steel bar is the main reason to lead the destruction of concrete structure.
混凝土中的钢筋锈蚀破坏是混凝土结构失效破坏的最主要原因。
2·A steel bar bundle can be arranged and anchored once via the clamping sheet.
所以它能将钢筋束一次安装穿束和锚固。
3·Because elastic modulus of CFRP plate are weaker than elastic modulus of steel bar, while strengthening beam is destroyed, the deflection is still strong.
由于CFR P板的弹性模量比钢筋的弹性模量小，加固梁破坏时的挠度仍较大。
4·The problem existed in many supervision and test for the thickness of protection layer for steel bar in engineering structure body are approached and some suggestion are proposed in this paper.
本文结合对大量工程结构实体钢筋保护层厚度的监督检测，对开展这项工作中存在的一些问题进行探讨，并提出了一些建议。
5·According to the testing and studying, ultimate strength, elongation and shrinkage on cross section of two kinds of steel bar were determined.
通过测试研究还得到两种钢筋的极限强度、延伸率和断面收缩率等其他高温力学性能参数。
