FIELD: construction.

SUBSTANCE: pedestrian span structure of the bridge with multi-braced main trusses of composite materials includes at least two multi-braced main trusses, the belts of which are made of angles and strips of the rectangular cross-section. The braces are made of one or more strips of the rectangular cross section, located on their wide sides in vertical planes parallel to the common plane of the truss, so that in the joints the parts of the belts and the braces are layered in different planes and bolted directly, without gussets; at least two transverse connections connecting the multi-braced main trusses; bearing bridge bed elements supported by the multi-braced main trusses and consisting of longitudinal ribbed panels fastened together and transverse beams. The bearing bridge bed elements are located at the structure bottom level, are made of composite materials, and the longitudinal ribbed panels are connected to the lower belts of the multi-braced main trusses and the transverse beams.

EFFECT: increasing the structure reliability and durability.
