Metal frame elements

Apart from load-carrying structures, the frames of buildings made of precast reinforced-concrete structures may include a system of braces. Braces are used to join flat transverse bents into a uniform space system capable of withstanding loads acting from various points in building, and transfer such loads to foundation. Schemes of braces are defined according to overall dimensions of building, column pitch, as well as by particular construction solutions (design of roofing, truss layouts. etc). Braces are used in combination with other structural elements of frame to provide for certain functions. The basic functions are: – Provision for geometrical strength of frame in longitudinal direction; |

Braces are classified into roofing braces and column braces (main and half-timber).
Roofing braces can be horizontal and vertical. Horizontal braces of reinforced-concrete non-slanting trusses are made as straight-line bars, whose different sections depend on truss pitch and load.
Vertical braces between trusses are made as separate elements composing a truss, whose layout largely depends on value of span (6 or 12 m).

Vertical braces between columns are employed to ensure -geometrical strength and stiffness of frame in longitudinal direction; -transfer forces from wind load acting on end of building; and, -longitudinal braking from bridge cranes on foundations. Cross braces and portal braces are typically made as coupled angle braces. Cross braces are intended for column pitch of 6 m; portal braces – for column pitch of 12 m, or, for the cases of making a passageway, or laying a process line.
