| Abstract | ||||
| The present work deals with the election of the optimum dimensions of concave enable roofs. In the static analysis, the energy method, based on, the minimization of the total potential energy (TPE) of structural elements , via Newton Raphson technique is used. The procedure is carried out by using the iterative steps to acquire the final configurations taking into consideration the effect of geometric nonlinearity of the structure Design parameters, such as both sag and rise to span ratios , initial tension in cables, distance between vertical ties, surface curvature, columns rigidity and their inclinations with horizontal, loading and support conditions are investigated. Numerical analysis of different concave cable roofs are performed. Finally the conclusions is outlined. | ||||
