IMPROVING THE CONSTRUCTIVE EFFICIENCY OF STEEL COMBINED TRUSSES
In this article, the rational constructive form of the combined steel truss with a span of 30 meters is received, with 59% fewer elements than the typical. Calculated regulation methods are offered stress-deformation state (SDS) combined steel trusses, which make it possible to increase their efficiency. Methods of estimated SDS regulation in combined steel trusses are given: change in the stiffness of the rodsand the creation of eccentricities in the nodes connecting the lattice to the upper belt and supporting eccentricities.
