Question

Accepted Answer

The question pertains to the expected stress and restrained movement on an expansion joint with dowel bar load transfer.

Total thickness of 300mm with M40 grade concrete and 31.5mm aggregate size.
Texture strength of cement concrete is 4.5 Mpa and compressive strength after 28 days curing is 40Mpa.
Expansion joint thickness is 25mm with dowel bar load transfer to one slab to another slab.
Dowel bar is 32mm dia, 500mm length plain bar with 330mm dowel bar full of greasing and 130mm dowel bar epoxy coated.
PVC dowel sheet size is 34mm x 100micron and inserted to prevent corrosion.
Water and dirt may enter the joint and affect the dowel bar.
Expected stress on the joint and resulting restrained movement needs to be determined.
