Theoretical aspects on the risk assessment of the reinforced concrete structures are presented. The earthquake capacity ratio is analysed for reinforced concrete framed structure. More attention is paid to the seismic shear force capacity and some new procedures are introduced to estimate the earthquake capacity of existing structures. The present seismic design and assessment of existing structures are done in Romania by using new codes in agreement with the Eurocodes. The impact of these new design codes in comparison with the previous codes is presented for reinforced concrete structures. The assessment and rehabilitation were performed on a office building RC framed structure built in 1971. The assessment of in-situ conditions showed up the main problems of the RC structure which consisted of inadequate concrete strength at some columns. The strengthening solution consisted in transversal confinement with composite fibre reinforced polymers of the columns. |
