Systematic strengthening scenarios for determination of most suitable retrofitting approach in a low-rise RC building

The aim of this study was to determine most suitable strengthening approach in a reinforced concrete (RC) building using numerical analyses. The entire process is illustrated using a case study for a five-story RC framed building. To determine the seismic performance level, numerical simulations wer...
