Abstract: In reinforced concrete (RC) frames, the masonry infill walls are used to fill the gaps between the two columns and one horizontal beam which form the single bay. Stiffness of this bay or reinforced concrete frame structure increases by filling the gap between the bays of a structure. The present study investigates that the influence of the infill wall in the vertical irregular tall structure with bottom soft storey and the behavior of (G+14) storey building subjected to seismic load. The study carries different type of models which are regular frame, regular full infilled frame, regular infilled with 15% central opening frame and regular infilled with 15% corner opening frame are analysed. Similarly the same study has been extended for vertical irregular bare frame, inverted vertical irregular bare frame. This study is made for a case applicable to earthquake zone (III), soil type (II) with importance factor (1) and M20 grade of concrete. The analysis is performed using the equivalent static method and response spectrum method as per IS 1893-2016 using E-Tabs 2015 commercially available software. The parameters considered for study are storey displacement, storey drift and base shear. The results obtained for storey displacement and storey drift, in the infilled frame are reduced due to presence of infill wall. However, as expected, the base shear is increased from bare frame to infilled frame.
