Analysis of Pre-Stressed Pseudo Box Bridge using Inverted-T Girder and Splicing Technique
The paper is for the structural analysis of continuous simply supported pre-stressed inverted-T girder using splicing technique. This paper represents variation of inflection points (point of contra flexure) for different variable loading conditions such as superimposed dead load, lane load, HS-20 truck load etc. The load (live load) for which inflection point changes its location greatly, amount of changes etc. also noticed and amount determined with several trials in this research. Finite element analysis method applied in this case for maximum bending and shear. The effect of false box action considered and found that due to false box action the reduction of bending stress shows lighter section of inverted-T girder. Without considering box action it shows inverted T-girder depth requires greater depth whereas false box girder action reduces its depth extensively.
