Abstract - This article present parametric study of different structural system, like moment resistance frame, moment
resistance frame with shear wall, moment resistance frame with bracing, frame tube with core, outrigger with belt truss.
It is very important to ensure the adequate stiffness of structure against the lateral loading caused by wind and
earthquake. In this study we have considered 10, 20, 30, 40 storey building for each system and compered to Base shear,
Displacement, and Storey Drift. In this study analysis and design done by using IS 456, IS 1893-2002, IS 875 Part – 3.

1. INTRODUCTION
In tall structure construction, proper structural system used more important to lateral stability, against the earthquake and wind.
Different lateral structural system are getting stability against the lateral forces in the tall structure. Behaviour of different structural
systems is having different load transfer mechanism. Generally in case of high-rise structure, stiffness requirement in terms of inter
storey drift and top storey displacements are important criteria to control.
1.1 Structural Systems
1.1.1 Moment Resistance system
Moment resisting frame is assembly of the columns and beams, joined by moment resisting frame connections. Building
performance during the earthquake, criteria of building will depend on material, strength, and ductility of structure components and
detailing of reinforcement. Moment resistance system are capable to resist to both type of load gravity load and lateral load safely.
And also control to structure parameter like displacement, storey drift.
When the building are tall, beam and column size becomes heavy, and steel area required large so that limitation of moment
resistance system to some height.
1.1.2 Moment Resistance System With Shear wall
Shear walls have very high in plan stiffness and strength, which can be used to simultaneously resistance large horizontal loads
and support gravity load. Shear wall can be defined as structural vertical member that is able to resist combination of shear,
moment, and axial load by the gravity and lateral load transfer to the wall from other structural member.
1.1.3 Moment Resistance System with Bracing
Type of bracing
(1) Concentrically braced frame
(2) Eccentrically braced frame
(1) Concentrically braced frame
Concentrically braced frame consists of diagonal brace member pinned to beam column junction. The braced impart high elastic
stiffness. Which are allowed designing the structure with small drift.
(2) Eccentrically braced frame
Eccentrically braced frame arranged that at least one of end of each brace is connected is to isolate a segment of beams called a
link. By combination of frame and truss action, they resist lateral force and by flexural and shear yielding develop ductility in link.
1.1.4 Frame Tube with Core
Frame tube is simplest is the perimeter closed spaced column and connected by deep beams. The system has large open floor
area with few interior columns design only for vertical load to carry, and total lateral load the exterior columns are designed.
1.1.5 Outrigger with Belt Truss
In this System centrally located share wall core with the peripheral columns through deep girder at top at some intermediate
level also, the lateral stiffness of multi-storey building can be highly improved. In steel buildings the core is made of vertical truss
and outrigger is horizontal truss. These outriggers mobilize the axial stiffness of column in resisting the lateral load and
simultaneously reduce the bending moment in column and beams.
