Modelling the strengthening of top coverings of historical structures with steel material by finite elements method

Conventional materials compatible with historical construction materials are usually used for restoration of historical structures. However, in some cases the conventional materials cannot be obtained, or the structure cannot be restored by conventional materials due to some structural problems. In this case, modern materials may be used in the restoration of historical structures. For this purpose, damaged prototype vault models were produced in this thesis, and three different strengthening proposals were prepared for these models according to various damage situations by using steel structure. These proposals were analyzed and evaluated in SAP2000 program by modeling with finite elements method. Structural models of a historical structure (Tokat Deveci Hanı) with the similar problem on the top covering were produced in accordance with the assessment results of the analysis, and strengthening proposals of the top covering by steel were prepared and analyzed. As a result of this analysis, more favorable results were obtained in strengthening the sample structure by steel rather than a conventional material in terms of structural behavior and material stresses.
