摘要

摘要: 钢框架内填钢筋混凝土深梁是一种新型的高层结构抗侧力体系。应用ANSYS程序分析了高跨比、厚度变化对钢筋混凝土深梁滞回性能的影响。研究结果表明，钢框架内填钢筋混凝土深梁随着几何参数变化，可以实现宽范围的刚度渐变调幅，其极限承载力、延性及耗能能力均发生变化。通过对比分析不同几何参数的钢筋混凝土深梁在反复荷载下的滞回性能，建议采用高跨比为1.5的钢筋混凝土深梁。研究成果可以应用于新建框架结构、建筑结构改造、加固与修复。

Abstract: Steel frame filled with reinforced concrete deep beam(RCDB) is a new kind of lateral resisting system for tall building structure.The programming ANSYS was used to analyze the hysteretic behavior of the reinforced concrete deep beam with different high-to-span ratio and thickness.The results indicate that the reinforced concrete deep beam with different geometric parameter filled in the frame can effectively affect the lateral resisting stiffness,ultimate bearing capacity,ductility and energy dissipation capacity of the frame structure and meet requirement of a wide range variation of the lateral stiffness of the structure.Based on comparison analysis of the hysteretic behavior of reinforced concrete deep beam with different geometric parameter,the value of high-to-span ratio 1.5 is suggested for the deep beam that can be used in the new structure,structural reinforcement as well.
