摘要:
随着使用时间的增长，RC框架结构会出现结构性能劣化、使用条件改变、抗震设防烈度提高等变化，结构会存在抗侧刚度不足，需要对其进行加固补强．Y形偏心钢支撑抗侧刚度高，耗能段独立于框架之外，耗能能力好，内填Y形偏心钢支撑加固RC框架结构效果好．在试验研究的基础上，提出了基于耗能段与框架梁连接节点承载能力的Y形偏心支撑加固RC框架的简化设计方法和构造措施．主要包括：耗能段与RC框架梁连接节点的构造和设计；耗能段的选取与设计，耗能段与支撑之间的连接构造；钢支撑的确定和设计，钢支撑与梁柱连接节点的构造和设计以及内填Y形钢支撑的布置．提出的简化设计方法可为类似工程的抗震加固提供设计依据．
Abstract:
As the RC frame structure using time become longer, the performance of RC frame presents degradation and such using conditions would change, as the seismic intensity, leading the RC frame lateral stiffness to deficiency. Because Y-eccentrical steel brace demonstrate excellent energy-dissipation capacity, filling it in RC frame can improve the structure seismic performance. On the basis of the test, the design method of Y-eccentrical steel brace reinforced in RC frames and nodes construction were developed. Construction and design method of link and beam nodes were presented. The selection and design of link, construction of link and brace were given. The design of brace, construction and design of connection of brace and column-beam were developed. Y-eccentrical steel brace were arranged. The specific design method of Y-eccentrically steel brace reinforced in RC frames provide a design basis for similar projects of seismic strengthening
