Rectification an 11-storey vertically deflected residential building

Abstract

The article presents a process of deflection eliminating (rectification) a vertically deflected 11-storey residential building consisting of two segments. Rectification consisted of tearing the building at the level where the prefabricated construction was resting on the monolithic foundation ribs and then of lifting the part of the building situated too low. The building corner situated lowest was raised by 572 mm. Rectification, carried out by means of 50 membrane jacks, restored the building's full functionality. The article presents also results of numerical investigations. Investigations were performed for two possible schema of the floors‘ work.
