FRAMEWORK STRUCTURE ABSTRACT OF THE DISCLOSURE A framework structure, for example, for roofs of industrial structures, includes tubular members connected to one another in joints and subtending an acute angle with one another so as to take up the tensile and compressive forces. The ends of the tubular members are flattened, and each tubular member has an intermediate portion between its tubular and flattened portions. The intermediate portion is formed by walls which converge linearly in a wedge-like manner. THe walls are inclined with ine another at angle of between 20° and 28°. It is especially advantageous when a joint is provided between the flattened end portions of a chord member and a diagonal member so that the axes of these members intersect.
