ABSTRACT
There is a colossal development in number of skew bridges or
flyovers; particularly in metropolitan and creating urban areas.
Because of straightforwardness in construction and requirements of
space accessibility in urban communities; expresswaytrades or grade
separators, the skewed slab bridges are adopted rather than regular
rectangular slab bridge. Literature survey revealed that studyof Skew
Bridge at different angle.

INTRODUCTION
Bridge is an important structure required for the
transportation network. Now a day with the fast
innovation in technology the conventional bridges
have been replaced by the cost effective structured
system. For analysis and design of these bridges the
most efficient methods are available. Different
methods which can be used for analysis and design
are AASHTO, Finite element method, Grillage and
Finite strip method.
OBJECTIVES
To Analysis & Design of different span of skew slab
bridge for an 15◦ angle
METHODOLOGY
In this research work, we have used STAAD PRO
software which is based on the application of Finite
Element Method. This software is a widely used in
the field of structural design and analysis. Now a day
this software is very much friendly for the analysis of
different type of structures and to calculate the result
at every node & element wise.

CONCLUSION
Skew bridges are required to cross the drains at any
angle other than normal. Effect of longitudinal
Bending moment by the variation of different span
length, When span is increases than Maximum
Bending Moment in X Direction ( in KNm/m) of
Skew Slab Bridge is decreases from 41.727 to 40.998
and Max Bending Moment in Y Direction ( in
KNm/m) .
