Seismic Strengthening of a School Building Damaged by the 2004 Niigata-Chuetsu Earthquake
Abstract eng: This paper deals with the strengthening of a school building damaged by the Niigata-Chuetsu Earthquake (Magnitude 6.8) of 2004. The building locates in the seismic zone where the intensity is registered 6+ on the 7grade Japanese intensity scale. The building was a 3-story reinforced concrete frame with total floor area of 2369m2 constructed in 1968. Numerous shear cracks were observed in columns and bending cracks in beams due to the earthquake and some columns were broken and failed completely. "Steel plate embedded reinforced concrete brace" was applied as a strengthening method and connected to the beam-column-beam joints together in order to increase the strength of the building. "Steel plate embedded reinforced concrete brace" was connected by post-installed anchors to the beam-column joints with the embedded steal plate. The joints were covered with concrete as well.
