PSC CONCRETE STRUCTURE CONSTRUCTED INTEGRAL ABUTMENT BRIDGE HAVING SHALLOW HEIGHT PSC I GIRDER DUE TO MOMENT REDISTRIBUTION THROUGH CONTROL OF MEMBER STIFFNESS

摘要

More particularly, the present invention relates to a PSC type I girder with high strength concrete and a steel pipe or steel composite pile to control the stiffness ratio between the upper and lower members. This is a technology that realizes low mold height by redistributing the moments that are high in cost. However, it is not economical to use PSC I type girders with high cost. However, it is possible to make a bridge structure with a pre- This type of girder bridges is a low rigid type PSC type I girder bridges which can reduce maintenance and economical efficiency by redistributing moment by modifying stiffness ratio of members.
