Construction technique of the beam bottom s reinforcement and strengthening for holding beams to change poles on steel reinforcement concrete;

In order to enhance the efficiency of nonlinear computation,the model is simplified in the project of supporting beam and removing column related to high structure.

The problems of reforming a mill building with reinforeced concrete bent frame can be solved effectively by a scheme of supporting beam and removing column,using adhesion supporting steel pole & bracket as well as artificial bored pile etc according to the characteristics of the project.

A good effect has been achieved by drawing column method combined supporting beam and removing column with bridle truncated column,adjacent concrete columns of the single story industrial building are continuously demolished.

The application of supporting beam and demolish column in reconstruction of old workshop;

This paper analysed and introduced engineering techniques in the process of rebuilding,including joist and brace columns and structure s reinforcement.
