SEISMIC DAMAGE OBSERVED ON PREFABRICATED INDUSTRIAL STRUCTURES AFTER 1999 EARTHQUAKES IN TURKEY AND PROTECTING MEASURES

摘要

structures was primarily due to the improper detailing in beam-column connections and lack of required lateral stiffness. In this study, extensive, serious damage and failures in prefabricated reinforced concrete industrial structures in the 1999 Marmara Earthquakes have been examined. To investigate the causes of the damage beside the assessment of practical imperfections, a comparision between the sets of criteria encompassed in the TEC-98, UBC-97 and EC8-98 Codes especially on the criteria of base shear force, displacement and loads acting on the nodes/connections has been made. In order to compare the above-mentioned codes a sample prefabricated structure is analysed. From this study, it is observed that the capacity dictated from TEC-98 is lower than the capacity of the other two codes. This deficiency is removed in TEC-2007.
