| Abstract: | According to mechanics property of the cable-supported lattice shells, the satisfactory method of double control on aim functions is proposed from the viewpoint of adaptation to engineering application. Mathematical model of cable tension optimization is set up. By means of advanced complex method, cable tension optimization is studied on the condition of determined section and an example is given. Those have a certain of reference value to the structural design and the engineering application. In addition, those can be used for reference to the system of spatial hybrid cable structures such as cable-arch structure, beam string structure and so on. |
