Abstract

The historical Ibrahim Aga Mansion purchased by the Chamber of Architects of Aksaray and wished to be used as the service building for the chamber. In this study, the strengthening project before the restoration of the building was prepared. The building had no foundations under the stone walls and suffered from cracks and decaying of the wooden floors. Since the existing structural system did not allow restoration of the building, strengthening and redesign of the structural system was the main priority. In the retrofit project prepared, the exterior of the building is totally preserved, and the interior which had low load-carrying capacity and functionality is redesigned for more functionality and a new structural system made of reinforced concrete and steel members was proposed. The foundations were combined into a raft foundation, the basement walls were changed into shear walls, basement and ground floors designed as a reinforced concrete whereas the roof columns, beams and floors were designed as a steel system. The exterior walls and the interior structural system were anchored together in order to prevent possible settlements and deformations that may occur in the future. The prepared strengthening project has been put into practice and the construction work is still undergoing.
