【 摘 要 】

The most significant constructive part of any large-span building is a system of coverage (roof). It defines the lasting quality of the building ensuring spatial rigidness, the exterior of the building, the size and condition of interior: the width of the span, the aperture of the required columns, determining magnitude and quality of sustained surcharge; and occurs to be the most labor-consuming and the most expensive segment of the construction activities, which consumes from 30 to 40% of the estimated cost.
