IMPROVING STRUCTURAL EFFICIENCY OF STEEL COMBINED TRUSSES
The article considers the issues of increasing the efficiency of steel combined sprengel trusses by developing rational design solutions by improving their stressed-strain state. The research methodology is based on a comparative analysis of technical and economic indicators in terms of material consumption of traditional typical and lightweight combined steel trusses. Three levels of adaptation are considered that affect the consumption of steel in the panels of the upper chord of a combined truss. Examples of achieving structure efficiency of trusses are given.
