| Abstract: | In this paper a theoretical solution for two normally intersecting cylindrical shells subjected to transverse moment on the branch pipe is presented, which based on thin shell theory. The accurate shell equations, boundary conditions and calculating methods are adopted so that the solution presented can be applicable up to d/D⩽0.8 and λ=d/(DT)1/2⩽8. The presented results are in very good agreement with experimental and numerical results for ORNL-1 Model. They are also in agreement with the results obtained by WRC Bulletin 297 when d/D is small. |
