Early structures in the medieval period of twentieth century were assumed to carry only the gravity loads.
However, today with the increase in urbanization along with the scantiness of land availability and high price rise, the
need of the vertical development arises for fulfillment of various needs of human activities. Owing to these situations,
advances have been in the development for the use of high-strength materials, lightweight material along with changes in
structural design and establishment of slender buildings. These innovative methods require critical analysis with
consideration of lateral loads such as wind and earthquake loads. Presently, numerous structural systems are available
which can be utilized for analysis of the lateral resistance of tall buildings. In this way, proper examination is required
for undertaking the consideration of proper type of structural system, which can be used to fulfill all our Structural &
Architectural parameters along with effective utilization of the material & technology that can be useful for sustainability
of the future. The present work, studies the response of the various structural system used in the buildings and its
comparison. Four different structural systems were investigated, which includes Structural Wall + Moment Resisting
Frame, Structural Wall System, Core Structural Wall system and Outrigger Structural System (Belt Truss System). 39
storey building having typical height 3.65m was considered. Moreover, Response Spectrum analysis and Static wind
analysis were also performed and comparison of different structural parameters such as Base Shear, Storey Drift, and
Storey Displacement were accomplished.
