Abstract

Although various types of segments and segment joints are employed, most segment joints are butt type joints with flat face or tongue and groove. Therefore, the forces in the lining are transferred through contact face at the joint. The force transfer at the contacted surface is very complicated phenomenon and may produce local high stress concentration. The local stress at segment joint of basic types segments such as rectangular or trapezoidal shape under various forces is investigated by photo-elastic method. The results show that smooth stress transfer can be obtained but high stress may develop in local area which should be considered in design.
