Convenient Seismic Retrofit Techniques of Existing Low to Mid-rise RC Buildings before/after Earthquake Attack

本研究的目的是提出一种新的抗震加固技术的基础上的基本思想的横向约束的低到中高层钢筋混凝土建筑。这一思想适用于柱损伤前/后，剪力墙，柱梁连接，钢支撑框架和钢筋的粘结强度。结果表明，该结构的抗震性能得到了很大的改善。其次，通过分析计算，提出了混合连接钢支撑框架的屈曲承载力。

The purpose of this research is to propose a new seismic retrofit technique for low to mid-rise RC buildings based on the fundamental ideas of lateral confinement. This idea is applied to columns before/after damage, shear walls, column-beam connections, steel braced frames and bond strength of reinforcement. As a result, great improvement in seismic performance is clarified experimentally. Next, buckling strength of steel braced frame on hybrid connection is proposed through analysis and calculation in this research.
