Modern Hybrid Structures for Buildings and Constructions

Objectives: The study considers the areas of improvement of engineering structures and formulates the principles for developing hybrid structures combining the elements with different properties in one constructive system. Methods: The common feature of all approaches that have been described in this study is that the elements included in the hybrid (combined) structure possess different properties. This study provides the detailed analysis of the strut frame hybrid systems with artificial stress control. Findings: The principle of creating hybrid structures implies the efficient combination of different elements in one system that results in lower specific weight of the structure, in simpler production processes, in lower costs of the objects and in higher durability of the structures. The authors suggested and investigated principally new constructive forms of flat and spatial light hybrid (combined) strut frame type systems and the methods of their manufacturing. Technical solutions have been protected by the industrial patents. The stress-deformed conditions of the cross shaped spatial strut systems have been investigated. The rational parameters of the structures have been identified that ensure maximum effect obtained due to the metal consumption decrease. The study investigates the properties of the constructive nonlinearity of the strut frame systems under the conditions of vibrations. New active shapes of the tie bars of the strut frame beams have been found. Application of these new shapes of the tie bars makes it possible to improve the strength of the system by 5…23 %. Applications/Improvements: The combined method of prestressing the strut system applying different techniques of artificial stress and deformation control has been proposed. Application areas for the pre-stressing of this type have been identified.
