Strength Behavior of High-tension Bolted Connections for I-shaped Plate Girder

초록

I-shaped plate girders are frequently used for the construction of the large span structures, especially large span bridges and railway bridges as they can be built up by (riveting or bolted connection) and welding the steel plates to get the desired sizes of the designers. Riveting or bolting type has many advantages such as avoiding both of the strength reducing problem during the construction and high maintenance cost after the construction as it is chosen over the welding type. However, such riveting has the problem of slipping around the bolted connection when the load is applied to the girder, which might cause strength reducing problems. Therefore, in this study, the slip behaviors of the bolted connection of the I-shaped plate girder, beside it’s strength behaviors were investigated through the FEM analysis program. Moreover, various effects of the vertical stiffeners’ interval on the strength of the girders were also examined along with this study.
