| Abstract: |
| Based on continuity and smoothness conditions of deflection on shell t the mechanical model was established using elastic analysis method for calculating shell stress distribution of large storage tank. The formulas for calculation of hoop and axial stress on stepped thickness shell were deduced by using deflection differential equation of short cylindrical shell. Taking a lank with volume of 15xl04 m3 for example, the detailed calculation process of tank shell was provided based on elastic analysis method. Compared the finite element method calculation results with the testing data, the feasibility and effectiveness of the method were verified. The results show that the method can accurately calculate the stress on lank wail, and can provide a reference for the design and checking of the tank wall. |
