Positioning of bearings for skew bridges

Positioning of bearings for skew bridges in beam and slab construction

yogendra borse

While designing bearings for a skew bridge with T-beam-cum-slab arrangement, correct positioning of bearings deserves special attention, so as to permit a longitudinal movement as well as a rotation of the beam ends simultaneously. 

1) Small Kew and Large Skew Comparison

2) Alternate for Large span and heavy loading

3) Comparison for wide slab or multi-girder bridges (Small span or load Vs Large span or load)

    a) For Single slab

    b) For multiple spans with concrete hinges (fixed bearings)

    c) For multiple span multigirder Hinged column
