Prefabricated structures are weak in strength in comparison with other types of structures. The most important problem with prefabricated structures is the nodal points problem. The greatest moment and shear strength occurs at the nodal points. Since prefabricated structures unable to meet the loads occurring at the connections during earthquake an unable to transmit them to other members, they undergo damage. To prevent this damage, it is necessary that these joints be made fixed appropriately to other principles of earthquake. During 6.3 Richter-scaled Adana earthquake on June, 1998, many prefabricated structures were damaged. In the Organized Adana Industrial Area, a number of prefabricated factory buildings were damaged or collapsed. In this study, focus was on the investigation of the buildings damaged during Adana earthquake in 1998, with the magnitude of 6.3, and this was examined by pictures and figures.
