［摘要］针对HRB500级高强钢筋在剪力墙与框筒结构体系中作为受力钢筋的安全性进行了分析。采用HRB500级钢筋代替HRB400级钢筋，应用EPDA软件对两个工程实例进行建模和弹塑性时程分析。分析结果表明，对于使用HRB500级高强钢筋的结构，在满足轴压比、构造要求及常遇地震的变形要求等条件下，结构在罕遇地震作用下的最大层间位移角满足变形要求，达到“大震不倒”的第三水准抗震设防目标。分析结果可为使用高强钢筋的结构的安全性提供数据支持和技术依靠。［关键词］HRB500级高强钢筋; 剪力墙结构; 框筒结构; 弹塑性时程分析; 层间位移角; 安全性中图分类号：TU511.32，TU375 文献标识码：A 文章编号：1002-848X(2015)22-0055-05
Analysis on safety of shear wall and framed-tube structure using HRB500 high-strength rebarYu Jinghai1, Wang Shaohua2, Wang Yan3, 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)Abstract: The safety of the HRB500 high-strength rebar used in shear wall and framed-tube structure was analyzed. Using HRB500 high-strength rebar instead of HRB400 ones, EPDA software was applied to establish the structure modeling of two engineering projects and elastic-plastic time-history analysis was carried out. The analysis results show that, for HRB500 high-strength rebar structure, in requirements of the requirement axial compression ratio and deformation requirement under frequent earthquake conditions, the largest interlayer displacement angle of the structure using HRB500 high-strength rebar under severe earthquake can satisfy the deformation requirement. It can achieve the third level seismic fortification goal. The analysis of the results can be used for the safety of the structure using HRB500 high-strength rebar to provide data support and technical depend.Keywords:HRB500 high-strength rebar; shear wall structure; framed-tube structure; elastic-plastic time-history analysis; interlayer displacement angle; safety
