The principal advances in the design and construction, as well as the static, vibrational, and buckling analysis of thin-walled structures and buildings in the shape of general and axisymmetric ellipsoidal shells are summarized in this review. These shells are particularly useful as internally pressurized vessels or as heads and bottoms of cylindrical tanks and vessels. Reinforced concrete and structural steel domes of buildings, air-supported rubber-fabric shells, and underwater pressure vessels are also made in the form of ellipsoidal, shells. Knowing the geometry of ellipsoids, one can solve various problems in physics, optics, and so on. Basic results of theoretical and experimental investigations of the stress-strain state, buckling, and natural and forced vibrations contained in 209 references are presented in the review. The influence of temperature on the stress-strain state of the shells in question is also discussed. Some parts of the review are also devoted to an analysis of the literature on the stress-strain state of ellipsoidal and torispherical heads of pressure vessels with openings.

Stress Strain State

The principal achievements of science and engineering in the sphere of design, construction, and static, vibrational, and buckling analysis of thin-walled constructions and buildings in the shape of hyperbolic surfaces of revolution are summarized in this review article. These shells are useful as hyperbolic cooling towers, TV towers, reinforced concrete water tanks, and arch dams. They are also used as supports for electric power transmission lines and as high chimneys. Several public and industrial buildings having the hyperbolic form are described in the review. The basic results of theoretical and experimental investigations of stress-strain state, buckling, and vibration are summarized. The influence of temperature and moisture on the stress-strain state of the shells in question is also analyzed. This review article contains 261 references.

Stress Strain State

In the recent years there appeared a tendency of widening the use of composite reinforced concrete structures in Russian construction practice, which keeps current the further investigations of their stress-strain state. In order to estimate the stress-strain state of composite reinforced concrete structures different methods are used: both analytical and experimental. In spite of material and labour costs field tests give the most correct indexes of the behavior of structures in actual operating conditions. The experimental investigations of composite reinforced concrete floors of civil buildings having considerable slenderness allow exploring new qualitative data of their stress-strain state. The authors offer the analysis of experimental investigations of composite reinforced concrete structures, in particular, composite reinforced concrete floor. They described geometrical and physical parameters of a test piece, the methods of measurements and tests, the experiment’s results are analyzed. The charts of flexure, stress blocks and distribution of moments are offered. The authors also give the results of numerical experiments and comparisons of stress-strain state of composite reinforced concrete floor with the results of field tests and their analysis.

Bending Load

The experimental investigations of steel samples under the influence of the bending load were conducted. It is demonstrated that in the event of the steel stress-strain state occurrence, its natural electric potential changes. The obtained dependence enables to determine mechanical stresses in a body of the object under study based on the electrical measurements data.
