Seismic performance of an existing low-rise RC building considering the addition of a new storey

Abstract In low-rise reinforced concrete (RC) buildings, structural design is generally performed considering the seismic effects as well as the vertical loads. However, there may be situations where the additional or unpredicted loads may be encountered during the service life of the buildings. The...
