Mechanical characteristics of Circular cable roof systems

Abstract

Abstract-A circular cable roof system in this study is a type of structures in which the part of entire roof can be opened and closed. The circular cable roof system with reverse curvature cable trusses can effectively carry vertical load in up and downward direction, the outer roof is a fixed lightweight membrane and the middle part is a roof system that can be opened and closed. The retractable roof is designed as the control system of optimum environment in which the part of roof can be open or closed to overcome extreme outdoor environment such as extreme hot, cold weather or strong sunlight. This research is analyzed the mechanical characteristics of retractable circular cable roof systems for the internal force of cables and the deflection of a roof according to hub or post heights. The structural advantages of a radial cable roof system, a spoke wheel cable roof system and a cable network system are compared for the results of geometrical nonlinear analysis by using Midas 2016 software.
