Utilization of Composite Materials in Saddle Shaped Cable Roofs

Abstract

A saddle-shaped cable roof formed by two orthogonal groups of cables joined with a compliant support contour is considered. The kinematic invariability of the roof obtained by prestabilizing the cables makes it possible to avoid heavy slabs of reinforced concrete in the construction of roofs and to use light composite materials. The main geo¬metric characteristics for a cable roof with CFRP load-carrying and contour cables and steel stabilizing cables are . determined by a numerical experiment
