Contact-concrete-wood-rubber-steel

Hello! There are fragment of bridge roadway - concrete slab, that stayed on the wood-rubber gasket.

How is right model of contact?

1 variant: frictional contact between top flange of steel beam and concrete slabe (modeling a load transfering) and spot bonded contact (modeling a fastening of concrete slab to steel flange)

2 variant: detailed modeling 4 materials concrete, wood, rubber and steel with folowing contact (without of modeling bolts):

It is not steel composite bridge, slab and beam bending separately.

Help me please with this contact.
