Influence of DDBD Approach in Seismic Assessment of Vertically Irregular RC Buildings
In recent years, the direct-displacement based design (DDBD) method has come up as an alternative to the traditional force-based design (FBD) method. Although several DDBD methods have been developed and used in the last few years, however in the context of open-ground storey (OGS) buildings, DDBD has received comparatively less attention from researchers. The most prevalent type of vertically irregular reinforced concrete building has been the OGS buildings, which have irregularity at the ground storey. The present numerical study investigates the applicability of the DDBD method for low-rise OGS buildings situated in Zone-V of Indian seismic regions. Different structural configurations buildings are adopted, having the same plan area but with different plan-aspect ratios. The non-linear static and time history analyses are performed under seven different spectrum compatible ground motions. The overall results of the study indicate the ability of DDBD to achieve the desired performance level for low-rise OGS buildings, except for a few cases. The plan-aspect ratio is also found to have a substantial impact on the seismic performance of OGS buildings during earthquakes.
