Thin Sheet Metal (Membrane) Suspended Roof Structures

Abstract

A membrane roof is a three-dimensional system of thin metal sagging sheets fastened along the perimeter to the supporting contour. The membrane can form the roof of buildings and structures of various shapes of the surface and in-plan outlines with spans of 18 to 300 m. The longer the span the higher the economic efficiency of the membranes, the thickness of which is as low as 1 to 5 mm.

The distinctive features of the structure are the most complete use of strength properties of a thin sheet in compression and the continuation in one material of load bearing and enclosure functions. Such a structure is able to resist all types of force actions, wind and seismic ones being among them.

The thin-sheet roof are easy to manufacture and erect.

The membrane structures are intended for civil and industrial buildings.

At present a wide complex of theoretical and experimental studies of the membrane structures is being carried out.
