Six columns on the first and second floors of a commercial building in Qingdao are required to be removed for functional purpose. The structural form of the building is RC frame,having 2 stories in the basement and 3 stories above the ground (4 stories partially) . Due to the columns removed,the span of the corresponding beam is increased to 18 meters. Bonded prestress technique is used to strengthen the original frame beam in order to sustain the increased loads,good result is obtained. The method used in this project can be referred by the reinforcing design of similar projects.
