Özet
Damages to prefabricated industrial structures caused by earthquakes in the last ten years in Turkey have occurred to an enormous extent. Among the causes of this damage, the inherent characteristic weakness of the load-carrying systems and constructing most of them according to the earthquake code applied before 1998 can be listed. The tragic situation that appeared after earthquakes emphasized that existing prefabricated constructions should be strengthened/improved according to the code which became valid after 1998. This study comprises three sections. The damage types in prefabricated reinforced concrete structures caused by earthquakes and the strengthening models (samples) that can be applied to these structures will be mentioned in the first and second sections, respectively. The last and analytical part of the study will be about the selection of the most often damaged industrial construction type which is preferred in industrial regions and the application of selecting strengthening methods performed by modeling these structures according to three different span types (1-S, 2-S, 3-S). The strengthening methods will be Shear Wall (SW), Steel Bracing (B), Steel Beam (SB) and Column Jacketing (CJ). All the systems will be calculated by using non-linear procedures (pushover analysis). The analysis performed by using a Software Package (DRAIN-2DX), will be applied to each frame in order to obtain load-displacement curves. The real hinge parameters will be defined using FEMA-356 to reflect the existing conditions. The results will be compared by considering the contribution of strengthening and especially system performance to displacement ductility.
