| Abstract: | In this paper the problems of shape finding for pre-stressed cable roofs are classified and one of the typical kinds is analyzed. The theories and corresponding procedures and equations for determining the prestresses in initial shapes of cable roofs are developed. Numerical examples show the effectiveness and rationality of the method presented in this paper. |
