Abstract - To overcome the need of connecting peoples,
in terms of horizontal loads, the multistorey building requires a position on which its negative effects are lesser. Since multistorey building is a host structure, its parts are not designed to overcome this problem, since it is not predefined that the tower will come over it in future. The other thing is the worst condition should not extend to other neighbouring structures
mobile phone creates a vital role among us. For this, the network service provider expands their business by extending the coverage of their network. In urban areas, the scarcity of land is the major issue now days and companies are approaching to the rooftop telecommunication, since it resolves the land use and to extend the coverage by approaching the height. Since it was not acknowledged before that the telecommunication tower will going to install over the roof of the multistorey building. In this work, to overcome this issue that creates a negative effect over the parts of the building after installation, by the help of Staad pro software, a plan is selected and designed not according to tower need and then the tower is applied over the roof in different positions to analyze the parametric values and select a position that creates least negative effects under seismic zone IV.
2. OBJECTIVES To show the work with the objective of an approach to find the efficient case, Response Spectrum Method is used on the selected host structure consist of telecommunication tower over roof. The points of comparison on which various objectives are followed up are as follows:1.
Key Words: Beam shear, Beam Moments, Efficient Case, Rooftop Telecommunication Tower, Seismic Forces, Square base, Staad pro, Torsional Moments.

The figurative analysis and survey shows that each and every person now have a mobile phone and for this, communication between then is now a major part of the economy. Without mobile, now it is very critical for one to connect his /her family. Due to this, the number of mobile tower is also increasing and the figures shows that it is always increase in number. Since telecommunication towers require a height to transmit the signals, it is now constructed increasing in height. Due to land consumption in urban area, the mobile towers are installed over the roof of the multistorey building to expand its range and to overcome the criteria of scarcity of land.

3. STRUCTURE CONFIGURATION In this paper, G + 12 storey residential building with 43.26m height having 5 bays of 3 m each in X direction and 7 bays of 3 m each in Z direction for complete 7 cases that are mentioned in table 1 and figure 1 & 2. Depth of foundation taken as 3m and height of each floor is taken as 3.66m. According to several cases mentioned in table, acronym such as S1 to S7 used to represent “Structure” and T1& T2 used to represent as “Type” were made. Indian Standard code 1893 (part 1): 2002 has used for seismic analysis of all cases,
The telecommunication tower which is installed on the roof is fixed into the columns or a framed structure over the roof. It is normally square in shape or can be inclined from its base, depending upon the design. It does not require guys to support it, it is now self-supported on its legs, preferably, triangular or square in shape. Due to its size and shape, it is heavy and can create a major disaster during an earthquake. Since seismic intensity is high
