Tall building developments have been rapidly increasing worldwide and also in India. Steel has a more
advantages material in world today it gives innovative framing systems, easy to assembling, high strength to weight ratio
availability of various strength and wider selection of sections and it is a environment friendly so steel is being used in
worldwide tall building. In past designers are only considering a gravity loads for the design of building. But now
improvisation in seismic and wind study, lateral forces is added in design of building. Tubular frames are one of the
common structural systems in designing tall buildings. Framed Tube and Bundled Tube are famous structural system.
Design of these systems requires precise analysis.
Tubular system is considering in two parts, exterior and interior which uses to resist lateral load and gravity
load respectively. In this study one steel building of each framed tube system and bundled tube system of optimum section
with 64 stories with symmetric plan area and identical loading condition using ETABS. Various parameters like
fundamental time period, maximum top story lateral displacement, maximum base shear, steel weight, and maximum
story drift are considered in this study.
