Since the concrete material has been eliminated from the locations situated around the middle of the cross-sections of Bubble Decks (BDs), the BD-type slabs are lighter than the traditional slabs. In the recent researches, Response Medication Factor (RMF) is generally determined for Reinforced Concrete (RC) structures with Moment Resisting Frame (MRF) and dual systems. The dual system mainly comprises MRF with Shear Wall (MRFSW) and at slab chiey with BD system. In this study, evaluation of the RMF values of RC structures using BD system was the main concern. The obtained results indicated that lateral strength of buildings increased by increasing the span length to story height ratio (L=H). Besides, the variations of span length and the number of stories had more Signiant elects than the variation of usage category of building on the RMFs of structures. Furthermore, the elect of span length was greater than that of the number of stories in determining RMF of an MRF. Finally, amongst the buildings with dual system structures incorporating MRFSW, the low-rise building structures had an RMF equal to 5 and both the mid-rise and high-rise building structures had an RMF of 7.
