某混凝土框架结构教学楼抗震加固设计与施工

Seismic Strengthening Design and Construction of a Concrete Frame Structure School Building

介绍了按照《建筑抗震设计规范》(GBJ11-89)设计的混凝土框架结构在不满足新抗震规范条件下进行的抗震加固设计与施工,采用了增大截面、粘贴碳纤维复合材料等加固方法,同时在施工中根据原结构情况、现场条件和加固要求采取了一些管理、技术措施,总结了工程中的有效手段和改进办法,其做法可作为同类加固设计施工的参考。

This paper mainly focus on the seismic strengthening design and construction of those concrete frame structure designed base on the old code of 1980＇ s which can not meet the current code. Section enlarging, carbon fiber composite bonding and other strengthening methods are illustrated in this paper as well as the introduction of management and technical measures which carded out according to the original structure, on site situation and strengthening requirements. Effective methods and improvements have been summarized and this case can be a reference to other similarprojects.
