STUDY OF PROGRESSIVE COLLAPSE ANALYSIS OF TRANSFER GIRDER SYSTEM RCC BUILDING

The structural behavior and analysis of multi-storey building components and supporting transfer girders have received added emphasis due to its importance in connection with buildings. The supporting transfer girder acts either as a full tension member, deep beam or as an ordinary beam in bending depending on the type of upper structure form and there relevant parameters such as span/depth ratio of the transfer girder, stiffness of the support columns, span of the shear wall. Progressive collapse is one of the main reasons for the failure of structure. It occurs due to removal/ damage of a column or a shear wall by fire, blast or vehicle impact. In this study, G+8 multi storey transfer girder system concrete building was analyzed using ETABS to predict the sensitivity of the structure to progressive collapse .Progressive collapse load combination was adopted as per GSA guidelines. Corner, edge and intermediate columns were removed separately at ground level and basement of the building. Viscoelastic dampers are used for improving performance of building during earthquakes. In the present study, effect of viscoelastic dampers on progressive collapse resistance reinforced concrete frame structure building is evaluated. This study can be useful for important structures.
