Reinforcing Effect of Ladders for Tanks with Floating Roofs in Case of Wind Influences
Abstract: The article considers an important problem of safe operation and reliability of vertical cylindrical tanks with floating roof. In the context of the issue of ensuring stability, two aspects of the problem are considered: clarifying the wind load in the case of an atypical design situation and using technological equipment as a reinforcing element. Spiral staircases for roof maintenance are considered as reinforcement. Refined values of the aerodynamic coefficient were obtained using computer modeling. They take into account the actual wind distribution in a group of tanks. The maximum discrepancy in hotel locations from the regulatory data was 20 %. Using the finite element method, the stability of the tank wall was assessed depending on the varying parameters of the ladders. For the studied tanks with a volume of 10 to 30 thousand m3, the possibility of using ladders as an element that increases stability is justified. In some cases, there was a 34 % increase in resistance to loss of stability. The recommended slope of the stairs has been determined in the range of 29…38°.
Keywords: stability, tank, finite element method, cylindrical shell, wind, aerodynamic coefficients, staircase.
