ABSTRACT
Basics of identified behaviour, performance and general rules of structural design of liners for egg-shaped, pear-shaped and other non-circular cross-sections are presented in this paper. The main causes of failure are pointed out based on experience gained so far in this field and feedback from researchers and manufacturers. Along with it, some accompanying conditions of installation and acting loads are listed. The primary approach to the assessment of liner load-bearing capacity with satisfactory safety margin is also included. Some basic and most common cases are distinguished to cover the area of liner application. Finally, the analytical approach is compared with rigorous FEM calculations.
