Effect of inadequate lap splice length on the seismic fragility of ground soft-story reinforced concrete frames

In this study, numerical analysis was used to derive seismic fragility curves for 3-, 6- and 9-story reinforced concrete (RC) frame with inadequate lap splice length and ground soft-story condition. The structural models were subjected to 15 far-field natural earthquake records. The peak ground acce...
