［摘要］针对HRB500级高强钢筋在框架、框架-剪力墙结构、剪力墙及框筒结构中作为受力钢筋的经济效益进行了分析。应用PKPM和STAT软件分别对若干工程实例进行建模分析，采用HRB500级高强钢筋代替HRB400级钢筋，在保证安全的基础上，对不同强度等级钢筋的用量进行比较和分析。分析结果证明，将HRB500级高强钢筋用于纵向受力钢筋时，材料强度充分发挥，节材效果明显，钢筋用量的节约比例约为10.0%，为使用HRB500级高强钢筋的结构的经济性提供数据支持和技术依靠。［关键词］HRB500级高强钢筋; 不同结构体系; 经济性分析; 钢筋用量中图分类号：TU375 文献标识码：A 文章编号：1002-848X(2015)22-0048-07
Steel consumption analysis of various structural systems using HRB500 high-strength rebarYu Jinghai1, Wang Shaohua2, Wang Yan3, Zhao Shanshan4, Xie Jian2, Ding Yongjun1(1 Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China; 2 School of Civil Engineering, Tianjin University, Tianjin 300072, China;3 Tianjin Architecture Design Institute, Tianjin 300074, China; 4 China Academy of Building Research, Beijing 100013, China)Abstract: The economical benefit of the HRB500 high-strength rebar used in frame structure, frame-shear wall structure, shear wall structure and framed-tube structure was analyzed. PKPM and STAT software were applied to establish the structure modeling of several engineering projects using HRB500 high-strength rebar instead of HRB400 one. On the basis of safety, the reinforcement amounts of different strengthes were compared and analyzed. The results show that use of HRB500 high-strength rebar can achieve good effect of saving material when it is used as longitudinal carrying bar, with strength of HRB500 high-strength rebar brought into full play, and the saving ratio is about 10.0%. The analysis of the results can be used for the economy of the structure using HRB500 high-strength rebar to provide data support and technical depend.Keywords: HRB500 high-strength rebar; various structural system; economical benefit analysis; reinforcement amount
