Chapter 9 Bearings and Expansion Joints Contents

Semi-integral design is used for prestressed concrete girder bridges under 450 feet long and for post-tensioned spliced concrete girder and cast-in-place post-tensioned concrete box girder bridges under 400 feet long. Use L-type abutments with expansion joints at the bridge ends where bridge length exceeds these values.

PRECAST CONCRETE MANHOLES

• When possible, avoid pipes entering into structure joints and corners, as this may compromise the structural integrity and watertightness of the structure. However, this practice may be necessary for certain installations and should be left to the discretion of an experienced precast concrete manufacturer.

WisDOT Bridge Manual Chapter 18 – Concrete Slab Structures

All concrete slab structures are limited to a maximum skew of 30 degrees. Slab structures with skews in excess of 30 degrees, require analysis of complex boundary conditions that exceed the capabilities of the present design approach used in the Bureau of Structures. Continuous span slabs are to be designed using the following pier types:
