- Purpose
The purpose of the present study is to develop a next-generation performance optimized horizontally corrugated steel web for concrete girder. The detailedyear-by year objectives are as follows:

☞ First year: Development of design method for horizontally corrugated web applicable to concrete box girder
☞ Second year: Development of connecting method between horizontally corrugated web with concrete flange

- Contents
♣ Development of optimum shape of horizontally corrugated web
☞ Development of various types of horizontally corrugated web which have buckling strengths higher than the yield strength without stiffeners through nonlinear analysis
☞ Determine of optimum shapes of horizontally corrugated web with excellent construct ability and economy
☞ Determine of stiffening method which have excellent bearing strength at load concentration regions and supports

♣ Verification of structural performance and applicability of girder using developed horizontally corrugated web
☞ Experimental test of steel box girder with horizontally corrugated web which was developed at first year
☞ Development of effective connecting method between horizontally corrugated web with concrete flange by studying existing vertically corrugated web

□ Results
Key result 1: Development of horizontally corrugated web applicable to concrete box girder
❃ Development of various shape of horizontally corrugated web
❃ Verification of horizontally corrugated web through FEM
❃ Development of optimum shape of horizontally corrugated web considering depth, thickness and steel type of web through economic analysis

Key result 2: Development of connecting method between horizontally corrugated web with concrete flange
❃ Varification of steel box girder with horizontally corrugated web which was developed at first year through experimental test
