Abstract - The sixth revision of IS 1893 (Part 1): 2016,
"Criteria for Earthquake Resistant Design of Structures" and
first code of tall building IS 16700: 2017, “‘Criteria for
Structural Safety of Tall Concrete Buildings” have been
published by Bureau of Indian Standards recently. In this new
code many changes have been included considering standards
and practices prevailing in different countries and in India.
In this dissertation work, performance of RCC buildings with
G+12 and G+16 storey’s has been evaluated by both equivalent
static analysis and response spectrum analysis method.
Performances of these building models are studied for zone II,
II, IV and V and compared. Entire mathematical 3D models
using the finite element software ETABS Version 17.

1.INTRODUCTION
In overhauling world, infrastructures have become
omnipresent and it is inevitable to imagine today’s world
without it. Buildings made from concrete is one of the basic
form of infrastructures which can be seen everywhere.
Process of construction of a building entails different
department such as architects, structure designer,
contractors etc. with all the help of these departments,
building is being erected such that it can withstand vigorous
vertical loads and ground motion which is the result of
earthquakes. Designer has to be very careful while
considering these forces as little miscalculations will lead to
failure of the structure because ground motions, being the
complex concept, needs to be analyzed in a very scrutinized
manner. Therefore, the resistance of a building and its design
as per the guidelines of seismic codes has become an
important research area. Sometimes, addition of members
other than beams and columns are required to resist these
produced lateral forces.
IS: 1893-2016, being the latest Seismic Indian Code, provides
amendments regarding the design of the earthquake
resistant building. Various amendments and new guidelines
were introduced in this code but the major one was related
to the dynamic seismic analysis. It stated that dynamic
seismic analysis shall be adopted for all the buildings other
than regular buildings lower than 15 m in height in seismic
zone II.

Previously, dynamic seismic analysis shall on be adopted if
the height of regular building exceeds 40m, otherwise static
seismic analysis shall be used. Therefore, while keeping both
the codes (new and old version of earthquake code), a
comparative study of static analysis (as per is: 1893-2002) &
dynamic analysis (as per is: 1893-2016) in seismic zone V
has been carried out. Various seismic parameters are to be
considered while designing earthquake resistant building
such as type of structure, material which is being used for
construction, type of foundation soil etc. Two different
methods, which are being used for making the structures
earthquake resistant, are:
1. Equivalent Static Seismic Analysis
2. Dynamic Seismic Analysis.
i. Response Spectrum Method
ii. Modal Time History Method
iii. Time History Method
2. COMPARISION BETWEEN IS 1893:2002 AND
IS1893:2016
The seismic codes are prepared with consideration of
seismology of country, accepted level of seismic risk,
properties of construction materials, construction methods,
and structure typologies etc. In India, IS 1893 (Part1)
Criteria for Earthquake Resistant Design of Structures is
used as code of practice for analysis & designing of
earthquake resistant buildings. In the last decade, the
detailed & advanced research, damage survey was carried
out by the Earthquake Engineering Sectional Committee of
