Seismic assessment and strenghthening of existing residential reinforced concrete buildings

TL;DRAbstract

The ability of assessment tools to forecast the vulnerability of buildings to prevent collapse during an earthquake is essential for existing buildings. Seismic vulnerability assessment techniques are classified as quick and exact assessment categories. The aim of this study is to develop a numerical tool that can be used to evaluate existing reinforced concrete buildings against earthquake shaking. The vulnerability and retrofitting of low to medium rise reinforced concrete framed buildings (3, 4, 6 and 8 story) located in high zones of seismicity in Iran was carried out. In order to reduce the time of assessment, a quick check of buildings is essential. To achieve this purpose a numerical tool has been proposed based on FEMA 310 (Tier 2 and 3) for RC framed buildings in earthquake prone areas. Quick assessment methods do not have the ability to deduce the exact deficiencies of buildings. Nonlinear pushover analysis is a useful tool for the exact evaluation of existing buildings to gi
