An Alternative Formulation for Determining Stiffness of Members with Bolted Connections

Abstract

In the present work a simple yet reliable mathematical formulation proposed for determining stiffness of members with bolted connection by subtracting the stiffness of solid cone from the stiffness of internal cylindrical portion (bolted portion). Three dimensional stress distributions of the member are considered in the present formulation. Mathematical validations of the results are done using formulations in the literature. It is found that, the present work gives satisfactory result for member with the ratio of total thickness of the clamped members to diameter of the bolt are approximately up to seven.
