Project Description:

This building has been constructed in 2016 and is composed of 4 blocks. There are five stories above the ground level and one basement. The construction area of the building is about 22,000 sqm.

The building was surveyed extensively by experts from Protek-Yapi Engineering Consultancy immediately after the 2023 Turkey-Syria earthquake. After conducting a comprehensive visual assessment, the following actions were done within three months after the earthquake as the use of this building was essential to organize the situation and activities of the city after the earthquake:

• One of the shear walls lightly damaged during the earthquake, was retrofitted by FRP.
• The concrete slab surrounding the above-mentioned shear wall, was retrofitted by FRP.
• For the nonstructural walls in several locations throughout the building with some minor cracks (0.5 to 5 mm) the resin epoxy was injected.
• For the wider cracks the mortar epoxy was used.
• The partitions, which were almost damaged, were demolished and rebuilt with additional supporting steel wall posts and the same material.
• False ceiling supports (which are mostly broken and/or damaged) were repaired using lateral bracing.
• The cover of the stair concrete slabs damaged after the earthquake, has been repaired using mortar grout.
• The stairs were retrofitted with steel columns and supporting beams. Also, these retrofitting columns were covered with architectural aluminum cladding.
• The front walls for the elevators were supported with steel plates and the surrounding shear walls were retrofitted by FRP.
