Abstract

It's a passive method to reinforce RC beam with glued steel plate and enlarging cross section while the post-stressed method is an active one.This paper introduced a reconstruction project of a long span RC beam with demolishing?column, which applied the advantages of the above two types.The beam- column joint is designed as a hinged one to reduce?the effect on bending bearing capacity of columns, and the transfer of external prestress is also set properly, which may be?served as reference for the design of similar reconstruction projects .
- demolishing column,
- post-stressed,
- plant reinforcing bar
