Abstract:

In this study, the progressive collapse potential of 10 storey reinforced concrete building with lateral load resisting systems are investigated. Two lateral load resisting system is considered named as bracing, and shear wall and their performance are compared with those of reinforced concrete building without lateral load resisting system with the same design load and seismic parameters. Linear static analysis and nonlinear static analysis (pushdown analysis) are carried out for different ground-story column removal cases. According to the linear static analysis result, members of both lateral load resisting systems have Demand Capacity Ratio values under permissible limit except RC building with the shear wall has not under the permissible limit of 2 for two cases. Pushdown analysis results show that all three types of structure have sufficient strength to resist progressive collapse. RC building with Bracing gives the better result as compared to the shear wall with reduced size of column for all cases.
