THE PROPERTIES SYNERGY OF STEEL AND WOOD IN THE CONSTRUCTIONS OF METAL-AND-TIMBER I-BEAMS WITH A CORRUGATED WALL

In modern bearing structures of frame widely used thin-wall steel profiles and constructions from glued timber. Each these materials has its own advantages disadvantages in the issues capacity, rigidity, heat engineering other physical characteristics. For further improvement efficiency buildings it is expedient to consider possibility combination positive properties timber metal due their optimal constructive combination.
 The purpose research determine effectiveness expediency using metal-and-timber I-beam construction building frames. uniqueness this lies synthesize corrugated wall, which well perceived transverse forces beams, belts mass or timber, are able perceive significant normal stress along fibers at expense intensity contribute guarantee bending-steep stability beams.
 a reliable profiled sheet possible use mechanical suppression rigid wall belts, connection with two-component epoxy adhesive, good adhesion both surfaces. As result walls double-walled beams there an increase rigidity profile, necessary height cut weight reduced. All significantly increases range double-branch efficiency.
 To ensure high corrosion resistance, galvanized used. Due thin combined 2-3 times less than same solid rectangular cut, reduces cost construction. Application promising direction buildings, combining two materials.
