The rational topology of combined steel trusses with spans of 12–30 m is offered in the work, which meets the criterion of minimum mass. It is shown that the rational calculation scheme for combined steel trusses is a scheme with inseparable upper and lower chords, and the connection of the lattice elements to them is hinged. Decreased for 30 m of combined truss, moments in the upper chord up to 28.4% compared to the truss when connected at all hinges. New methods of stress-deformed state (SDS) control in combined steel trusses are proposed. According to the results of numerical studies found that hat when adjusting the stress-deformed strain state in the combined steel truss with a span of 30 m, it is possible to reduce the moments in the extreme panels of the beam stiffness up to 13.8%. It is shown that to increase the efficiency of the estimated regulation of SDS it is rational to apply the optimal design. The practical implementation of the proposed methods of SDS regulation during construction confirmed its effectiveness.
