NEW SEISMO-SAFE SYSTEM OF PREFABRICATED INDUSTRIAL HALLS WITH TEST-PROVED MODELS OF CRITICAL CONNECTIONS

ABSTRACT

Heavy damages and total collapses of prefabricated industrial halls was observed in past earthquakes widely in the world. Regarding the present need, conducted was specific large-scale research project leaded by the first author, “Development of optimal prefabricated system of industrial halls applicable in seismic zones with higher intensity, including seismic intensity IX“, supported by well-known Serbian PUT INZENEERING construction company. Based on conducted intensive testing in Skopje RESIN laboratory of constructed large-scale prototype models of critical connections, the advanced novel seismically resistant (NSR) prefabricated system of industrial halls has been successfully developed. Improved seismic safety of the system was achieved by combined application of new concepts of critical connections along with added new integrating segments of the global structural units.
