PARTIAL SUBSTITUTION OF STEEL REBARS IN BEAM-COLUMN JOINTS BY USING STEEL FIBERS FOR THE SUSTAINABLE DESIGN OF RAILWAY BRIDGES

Abstract eng:
In this study, an attempt was made to reduce the amount of longitudinal and shear rebars in the beam-column joints by partially replacing steel rebars with steel fibers so that the congestion at the joints can be avoided without affecting the mechanical performance. The experimental results showed that the overall performance of the beam-column joints with steel fibers was improved although the amount of steel rebars was reduced. It is found that the removal of certain amount of steel rebars can shorten the construction period, lower the overall construction cost and enhance the durability of the structures which plays an important role in the sustainable design of bridges.
