The corrugated steel web is widely used nowadays as a structural element in the bridges due to its many favourable
properties. Prior researches have shown that girders with steel corrugated webs (BGCWs) are an effective improvement in
resisting the buckling when compared to conventional girder bridges. The studies have also shown that BGCWs buckle with
three different modes; local, global and interactive buckling modes. This study is conducted to investigate the buckling
behaviour of a non- prismatic bridge girder with double corrugated steel webs (BGDCWs). In this study the BGDCWs placed
parallel and transverse having best taper ratio is obtained and arrangement of webs having least performance is strengthened
using double corrugated stiffened girder (DCSG)and double corrugated composite girder (DCCG). The finite element modeling
and analysis were carried out using the software ANSYS workbench 16.1. The results obtained shows that the taper ratio 3 is the
best in both the cases of double web placed parallel
