Теоретичні дослідження міцності металевих комбінованих шпренгельних систем

The work is dedicated to improving the methodology of calculation of regulation of the stress-strain state of metal trussing statically indeterminate composite structures. When searching for project management considers the problem of lowest mass systems with given geometry and material designs make rods. Problem calculating the regulation of the stress-strained state of the system is reduced to the solution structures in a deformed state by a system of equations and statics, and those efforts. In the thesis the method, algorithm and software to adjust the SSS SICS elements in metal trussing statically indeterminate composite structures based on sustainable design through incremental changes in their geometric schemes, elastic properties and external loading. Based on the algorithm using mathematical modeling carrying capacity of cross-sections of trussing metal SICS the influence of design scheme, the geometrical and mechanical characteristics, and mode of application of the load on the stress-strain state of the system. During theoretical studies established the basic dependencies for selection of physical and mechanical properties and geometrical parameters trussing combined statically indeterminate structures to achieve exactly moment and equally buse states.
