4. ABSTRACT
• Earthquake resistant structures are design to
resist structural collapse due to earthquake
forces.
• In this present study, analysis using STAAD.Pro
for G+3 terminal building construction at
Silchar Airport.
• Analytical modeling are adopted to control such
unpredictable magnitude, direction, time
occurrence of seismic forces on structure.

5. INTRODUCTION
Building Construction plays a big role all over
the world, where it’s a part of living a life for
human kind since human civilization were
found.
Nowadays, daily new applications &
techniques are speedy developed for building
construction economically, rapidly & fulfilling
with need of community engineers as like as
architects to do their design work, planning &
processing & layout, etc for construction of
building.

6. • Earthquake or seismic originates below the earth surface due to
the rupture of bed-rock. The origin below the surface where
earthquake places called seismic focus or Hypocentre & point
towards the earth surface exert is called Epicentre.
• Ground motions can measure in acceleration form, velocity or
displacement. Whereas the earth scientists are very interested in
capturing earthquake size & its origin worldwide,
EARTHQUAKE
also to measure the
feeble ground
displacements
eventually at great
distances from its
epicenter.

8. Here, the design & analysis of building at Silchar Airport having G+3
storey frame is taken up. The building plan having (54.30m X 9.185m)
consists of columns which built monolithically to form a network. The
numbers of columns are 30 which is a commercial building under Seismic
Zone-V. The designing aspect has made using the software on the basis
of structural analysis design i.e. STAAD.Pro. Whereas IS-1893:2002
provisions for earthquake resistance design for building aspect are
considered.
• Ductility –based such design are consider according to IS-13920.
Objective of the Study

9. Elastic behaviour in building during
earthquake

10. METHODS OF ANALYSIS OF STRUCTURES
There are several analytical approach has develop
from time to time in many countries for examine
earthquake resistant buildings. In India, IS: 1893
(Part-1)-2002, for earthquake resistant analysis &
design are taken out through-
– Equivalent static analysis,
– Linear dynamic analysis,
– Non-linear static analysis,
– Non-linear dynamic analysis,
– Seismic coefficient method,
– Response spectrum method,
– Time-history analysis.

11. Seismic Coefficient Method
• It is a type of static procedure where all horizontal &
vertical forces are to be calculated as seismic
coefficient for making consideration of seismic action
caused by earthquake. The assumptions are-
• Design must be carried out as per IS: 1893(Part-1)-
2016 provisions.
• It to be assume that the structure is rigid
• There should be perfect flexibility between the super
structure & foundation, i.e. the integral system of action
and each & every point on the building behaves same
accelerations during seismic motion.
• Buildings must not heavily mass weighted & beam-
column should maintains equal in width, etc.

12. Loads Acting on Building
Building loads can be divided into various types particularly
based on the orientation of each members of building where
the structural action or the forces which induce the vertical &
horizontal load i.e., lateral loads. Classification of loads are-
– Dead load, Live Load
– Snow load
– Wind load
– Seismic load
– Seismic & wind (overturning) load
Load Comibnation-For two load cases = 1.5(D.L + L.L)
• For three load cases = maximum of 1.2 (D.L+ L.L+W.L)
(or) 1.2 (D.L + L.L + EL)

– Designing using Software’s like STAAD.Pro in which
reduces lots of time in design work, easily detailing of each
