HRB500钢筋在工程中应用的效益分析

Benefi t Analysis of Application of HRB500 Reinforcement in Engineering

HRB500钢筋是一种强度高、延性好的热轧带肋钢筋,目前该种钢筋在国外已经大范围地应用于桥梁以及房建等土木工程领域中,然而该种钢筋在我国尚未大规模地推广应用。为了响应国家节能减排、节省资源的号召,以北京城市副中心二期建设项目为试点,对HRB500钢筋在工程中应用的效益进行了分析。分析结果表明:HRB500钢筋应用于混凝土工程中不仅是节能减排、绿色施工的必然选择,具有良好的社会效益,而且能够大幅地节约钢材、降低工程造价,具有良好的经济效益。

HRB500 steel bar is a kind of hot-rolled ribbed steel bar with high strength and good ductility.At present,this kind of steel bar has been widely used in civil engineering fields such as bridges and housing construction abroad.However,it has not been popularized and applied on a large scale in China.In response to the national call for energy conservation,emission reduction and resource conservation,taking the second phase construction project of Beijing Urban Sub Center as the pilot,the social and economic benefits of the application of HRB500 reinforcement in the project are analyzed.The analysis results show that,the application of HRB500 reinforcement in concrete engineering is not only an inevitable choice of energy conservation,emission reduction and green construction,and has good social benefits,but also can greatly save steel materials and reduce construction costs,and has good economic benefits.
