Abstract: Structural development in the metro city has rapidly increased as there are many high-rise construction projects that have been carried out. Structural analysis is the fundamental part of the design of the high-rise structure which shad the same height and same geometry. It is effective solution for residential purpose however; few of the challenging problems have been facing such as vehicle parking and other basic enmities space. Therefore, many structures provide a common either in single, multiple floors, or underground basements parking in this kind of structure often seen in the residential as well as a commercial complex. In present paper to study on considering effects of influence parameters like the height of the tower, connection with basement and depth of basement with two parallel towers (Twin-Tower) having a common basement. The main object of the study the twin tower in linear dynamics earthquake analysis have been considering on the behaviours of structure G+20, G+25, and G+ 30 stories symmetrical twin tower without an underground basement, with 2, and 4 number of Basement. The seismic response of the superstructure was studied by observing the variation of internal stress results such as base shear, storeys displacement, storeys drift, and storeys shear. The analysis results obtained from all models were performed by using various linear dynamic structure analysis approaches such as Equivalent Static Force Method (ESFM), Response Spectrum Method (RSM), and Time History Analysis (THA).
