碳纤维布加固钢骨混凝土柱受剪有限元分析

Finite element analysis of reinforced steel reinforced concrete column by carbon fiber reinforced concrete column

对既有结构的维修加固已经成为土木建筑业的投资与研发的主体,被认为是缓解资源实现可持续发展的有 效手段.我国因SRC结构的用钢量较大,随着我国超髙层建筑的发展, SRC结构也越来越受到我国工程界的重视,并 在一些高层建筑中采用.但因为钢骨与混凝土的粘结性能不好,容易导致粘结滑移,致使构件破坏.本文对碳纤维布 加固钢骨混凝土柱进行了有限元分析,采用简支梁式加载方式,将碳纤维布加固钢骨混凝土柱与未加固进行对比并 得出结论,可供工程设计进一步参考.

The maintenance of existing structure has become the main body of civil construction investment and development in many countries,it is the effective measure to realizing sustainable development. In our country, the structure of SRC is used widely in steel,and with the development of supertall buildings in our country,the structure of SRC is becoming more and more appreciated by the engineering community. But the bonding proper-ties of steel bone and concrete is not good,it is easy to make the bonding slip,and causes the component to be damaged. In this paper,the writer makes finite element analysis for the carbon fiber cloth reinforcing steel rein-forced concrete column,and compares the carbon fiber cloth reinforcing steel reinforced concrete column with the unreinforced concrete column, and draws some conclusions that can be referenced.
