The need of multi-storied buildings is increasing in the present scenario of rapid growth of urbanization, increasing land cost, and depleting agricultural land. Wind and seismic effects govern the structural configuration of multi-storey buildings. Various structural systems like wall-frame, tubular, outrigger-belt truss, diagrid structure, etc. are developed to resist lateral loads efficiently. A conjoined structural system is developed by joining two or more individual buildings at different levels along the height. This paper presents the seismic behavior of a conjoined structural system for varying heights of buildings. The individual moment resisting frame structures with plan dimensions 30 × 30 m and having 30, 40, 50, 60 storey are considered for the present study. In addition to individual buildings, conjoined buildings developed by connecting individual buildings at top are considered. Four individual buildings are arranged in two rows, with two buildings in each row with a clear spacing of 20 m between them and connected at top using link structure. Seismic behavior of individual and conjoined buildings is compared and presented. Lateral loading due to earthquake is considered as per IS 1893. ETABS software is used to model and design structures. Comparison of natural periods, earthquake forces, storey shear, lateral drift, and inter-story drift for individual buildings and conjoined buildings is made. Based on comparison of analysis results it is found that a conjoined structures can resist lateral forces more efficiently with an increase in the height of buildings.
