Abstract

Abstract

Structure inspection and appraisal of a steel plant's old factory building was carried out, the results showedthat for reinforced concrete members such as columns, roof trusses, trussed girders and roof panels, cracks occurredalong steel bars, peeling of concrete covers and corrosion of steel bars. Also there were many defects of roof bracingsand bracings between columns, and the number of bracings was insufficient. There were many serious securitytroubles to the factory building. A reinforcement design was made based on experiences of earthquake disasters. Thelower concrete columns were strengthened with section enlarging and steel plate, the upper concrete columns, rooftrusses and trussed girders were strengthened with steel frame. The old concrete roof panels were replaced with thesteel ones, and seismic measures were improved. Good result was obtained for the strengthening of the factorybuilding, and the design could be referred by the strengthening of similar structures.
