-A bearing type connection is one in which the bolts are in shear because there is not significant enough friction in the joint to prevent slip.
-The maximum shear in the bolt occurs at the contact surface of the connected plates. The strength capacity of the bolt, then, is the shear strength of the bolt where the shear is at its maximum.

Assumptions in Design of Bearing Bolted Connections:
I. Negligible Friction between Plates
II. Uniform Shear across Cross-Section
III. Equally Shared Load by Bolts in a Group
Explanation:
I. Negligible Friction between Plates:
The assumption of negligible friction between plates is made because it simplifies the analysis of the connection. In reality, there will be some friction present between the plates, but it is assumed to be small enough to be ignored.
II. Uniform Shear across Cross-Section:
The assumption of uniform shear across the cross-section is made because it simplifies the analysis of the connection. In reality, the shear may not be uniform, but it is assumed to be so for simplicity.
III. Equally Shared Load by Bolts in a Group:
The assumption of equally shared load by bolts in a group is made because it simplifies the analysis of the connection. In reality, the load may not be equally shared, but it is assumed to be so for simplicity.
Conclusion:
All three assumptions (I, II, and III) are made in the design of bearing bolted connections to simplify the analysis of the connection. However, in reality, there may be some deviations from these assumptions, which should be considered in the design process.
