Abstrakt:

Beam is one of the most common wooden structures. The use of beam structures is relevant in the flooring and roofing of buildings. A disadvantage of using wooden beams is the impossibility to cover a span of more than 6 m without expensive factory-made structures (glued beams, composite beams, metal-and-wood beams, LVL beams, etc.). The study proposes a wooden structure of a composite girder truss with a span of 9 m, assembled from planks with the use of steel dowels directly at the construction site. The purpose of the study was to experimentally determine the strength and deformability of wooden girder trusses with a span of 9 m. The following methods were used: experimental investigations of the stress-strain state of beams. As a result, brittle fracture was noted in the area of the support chord junction with the span chords under the action of breaking load equal to 14.52 kN/m. The values of tensile and compressive strength of wooden girder trusses were experimentally determined to be 35.35 MPa and 25.14 MPa, respectively. The developed wooden girder trusses are recommended for use in the flooring of buildings with a span of 9 m.
