Abstract

Annotation. Purpose. Representation of the interconnections of new developed know-how development technologies for solving complex problems of nonlinear dynamics of structures for engineering and construction. Methodology. As methods of solving design problems of nonlinear dynamics of structures, new structural elements (like the known method of lines) were used which, together with the method of compiling ordinary differential equation system of motion with additional algebraic equations, were modified to a special technique of construction-nonlinear designation, called the technique of elements, subsystems and sets of properties, TESASP. These methods together with purposeful tests are combined into a single diagnostic complex.Findings. The list of modern dynamic loads on structures is given, directions of perfection of all complex of researches are created: nonlinear calculations in time domain, dynamic tests, specification of variable parameters of object and creation of simplified engineering models. Originality. The path of the transition from the erroneous application of linear schemes and methods to the correct methods of accounting for the dynamics of all four groups of nonlinearities is indicated. The connection of diagnostic tests with conditioning, monitoring and operative trouble-hunting is shown. Practical value. The results of the research are grouped in three directions - for designers, testers and operators of comfortable and accident-free structures. It is suggested that investors and their managers should pay special attention to the described innovative directions of work in the building industry.
