The article presents the four stages of creation and development of the theory of plate and shell which led to the development of a mechanism of calculation of spatial structures of large span buildings and constructions on an advanced level. Each of the stages of the unique buildings calculation method development includes a description of the main achievements in the sphere of structural mechanics, the theory of elasticity and resistance of materials which became the basis for the modern theory of calculation of plates and shells. In the first stage the fundamentals of solid mechanics were developed; this is presented in works of such outstanding scientists as G. Galilei, J.-L. Lagrange, R. Hooke, L. Euler, Kirchhoff, A. Law etc. Development of the theory of plate and shell would be impossible without these works. But absence of such construction material as reinforced concrete did not enable engineers and architects to create a thin roof. Thickness of coverings was intuitively overstated to ensure durability of buildings. The second stage is interesting by formulation of the general theory of calculation of plate and shell and by transition from the working state analysis of structures to the limit state analysis. Beginning of use of reinforced concrete resulted in decrease of a roof thickness to the diameter of its base, compared to buildings made of stone and brick. The third stage is characterized by development of computational systems for calculation of strength, stability and oscillations of core and thin-walled spatial structures based on the finite element method (FEM). During this period a design of buildings and constructions with spans over 200 m with the use of metal was begun. Currently, or during the fourth stage, structures with the use of metal and synthetic materials for spans up to 300 meters are designed. Calculations of long-span buildings and structures are performed using FEM and taking into account different types of nonlinearity. Each stage selected from the history of construction is exemplified by completed projects, hereat characteristics of roofs indicating the applied construction material are given. Transition from natural stone to concrete, metal and synthetic materials in construction of large-span buildings is illustrated in the table. At the end of each stage the scientists’ and designers’ main achievements in the sphere of science, construction and engineering education are shown.

The article covers the relevant problem of dynamic monitoring of buildings and structures. Items exposed to dynamic monitoring primarily include high-rise buildings and structures, as well as buildings and structures exposed to crane loads.The authors provide the general procedure of dynamic monitoring and describe its principal stages. The whole succession of actions that constitute the monitoring of the technical condition of buildings and structures can be split into several stages to be stretched over the time period. The authors demonstrate the technical specifications (including dynamic parameters) of a building or a structure in the process of its operation in the form of a graph. The authors propose their methodology of dynamic monitoring that is considered on the basis of a simple example. The authors argue that the more technically sophisticated the item to be monitored, the tougher the requirements designated for its safe operation; therefore, the interval between the stages of monitoring should be shorter. Unique structures may need monitoring using automated stationary systems to be designed within the framework of special-purpose projects.
