| Abstract | Many existing reinforced concrete slab-column frame buildings may have been designed without consideration on seismic loadings. Therefore, it is of importance to evaluate seismic performance of these buildings. The pushover analysis is one of the procedures that is strongly recommended by ATC-40. To perform this procedure, based on the literature, one modification of equivalent frame model is developed to analyze the slab-column systems. Then, a procedure based on this model and modeling techniques recommended in ATC-40 and FEMA-273/274 for seismic evaluation slab-column buildings is adopted. One typical flat-plate building and one typical flat-slab building are selected and used as examples. The obtained capacities of buildings are plotted in the form of normalized base shear coefficient and roof drift ratio. The results show that slab-column frame buildings have low lateral capacity and low drift compared with traditional beam-column frame buildings having the same overstrength order. Punching shear failure is observed in the interior connections of flat-plate building. The evaluation also shows that slab-column frame which included the shear wall can increase lateral and roof drift capacities significantly. Therefore, a strong recommendation is to design slab-column systems combined with shear wall systems. It can also be concluded that the exterior connections have a high possibility to be damaged in the slab-column system. This study also reveals that the damage distribution starts and concentrates in certain stories having high connection rotations. |
