Abstract
The paper descibes some analytical investigations on plane cable systems under uniform load.
By deducting expressions for the theoretical quantity of cable steel it is shown that this quantity is the same for the suspension systems, the fan system and the harp system provided that all systems are made as pure cable systems (with all elements in tension) and with the same horizontal force.
Furthermore, it is investigated how the arrangement of the supports for the fan shaped cable system and the stiffening girder affects the distribution of the normal forces in the girder. It is hereby shown that a considerable reduction of the normal forces can be achieved by anchoring the back stay to an anchor block instead of the sifffening girder.
