Özet

This study numerically examines the pre- and post-strengthened states of a low-rise RC building. Material characteristics were obtained through on-site examinations and laboratory tests. Damages in certain columns, beams, and slabs resulting from moisture and dampness, as well as cracks in the columns due to reinforcement corrosion, were identified. Numerical models created to represent both states of the building were subjected to non-linear static push-over analysis. While the pre- -strengthened building was found not to satisfy the “Controlled Damage” performance level criterion for a DD-2 ground motion, the strengthened building met this criterion. Based on the moment distribution analysis of the strengthened foundation, it was concluded that the foundation reinforcement is adequate. As a result of the soil investigation parameters and static analysis of the foundation, it was determined that the foundation safety was ensured for soil pressures.
