Comparative Analysis of RC Structures Progressive Collapse for Different Seismic Zones

  Pavithra B.R,  Manjula K

Now a days, buildings exposed to progressive collapse is produced by immediately deleting some vertical loads due to ultimate loads and results gives the failure of structural buildings. G+8 storey of building is considered for progressive collapse analysis by using dynamic methods. The sudden column removal gives damages of nearest beams up to some storey levels building conduct different seismic zones. The dynamic analysis is carried out using E-TABS Version 9.6.0 software. Demand capacity ratios (DCR) of multi typical storey RC framed structure are calculated approximately by using general service administration guidelines. The comparative analysis of frame structure in different ground motion zones for progressive collapse. During earthquake effect, the causes of progressive collapse are checked and safe and unsafe structural members are to be studied for different models are analyzed in different ground motion zones.

Keywords- Progressive collapse, RC Building, ETABS, Column removal, Dynamic analysis.
