چکیده
This paper reports a study into the effect of winding type on stressed-strained state wall steel cylindrical tank filled with oil to predefined level. The shapes free oscillations in and natural frequencies structure were analyzed. Stress was estimated basis finite-element simulation deformation three-dimensional structural model under influence distributed pressure inner surface stresses outer wall. induced by various types, taking consideration level loading, step winding, mechanical characteristics thread. investigated at its full filling oil, half-filling without oil. Three options simulated: single, double, triple intervals. Two types considered: made from high-strength wire composite It established that when interval, stress does not exceed 34.2 % yield strength. At same time, height loading significantly affect Applying thread leads an increase up 47.2 strength but makes it possible reduce mass winding. When increases only 3.6 %. results reported here make effectively use pre-stress order improve dynamic studied structures, their windings different materials

Study on the dynamic behavior of cylindrical steel liquid storage tanks using finite element method
Dynamic behavior of ground supported cylindrical storage tanks (CST) is of crucial importance because of its applications in industrial complexes. Seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. Five CSTs with different height to diameter ratios, three CSTs with the same height and diameters but various fluid heights and one CST with t...
متن کاملField Study and Evaluation of Buckling Behavior of Cylindrical Steel Tanks with Geometric Imperfections under Uniform External Pressure
Construction and assembling process of shell structures has caused main problems. In these structures, there is no possibility for the integrated construction due to their large shell extent and they are built using a number of welded curved panel parts; hence, some geometrical imperfections emerge. Most of these imperfections are caused by the process of welding, transportation, inappropriate ...
