Introduction. Load carrying capacity ― the ability of structures to resist of limit load. Modern design standards recommend based plastic calculation when the load carrying capacity may be calculated in in general, including all possible of different forms of destruction. Calculation of the upper bound of the limit load for many cases can often be carried out in a closed form formula giving the final results. On this basis we can construct an economical and efficient process of preliminary design, which addresses to various forms of competition exhaustion load carrying capacity resolution.
Problem statement. During operation structures may lose they load carrying capacity, stability. These factors can prevent further exploitation. Assess the suitability for further use is load carrying capacity which can be evaluated by kinematic method of limit equilibrium theory.
Purpose. Techniques for load carrying capacity assessment of cylindrical shells taking into account various possible forms of load carrying capacity.
Materials and methods. Method of calculation developed on based load carrying capacity with kinematic method of limit equilibrium theory by which we can evaluate the load carrying capacity of cylindrical shells.
Results. The proposed method and the resulting value are methodological in nature and not intended to sweeping generalizations however, we can see that the load carrying capacity of cylindrical shell can be achieved with different combinations of thickness and cross-sectional area tightening.
Conclusions. The method of load carrying capacity calculation gives an ability for cylindrical shells design. Specified load carrying capacity of cylindrical shell can be achieved by various combinations of thickness and square section of elements in tension. The resulting ratio for simple assessment of limit loads allow to formulate of optimization problem of finding the most economical design according to a given load carrying capacity.
