[Abstract]:In order to understand the mechanical behavior of the internal concave spoke tensioning structure, the approximate relationship between the initial prestress and the configuration of the inner concave structure is established, and the rapid estimation of the initial prestress of the structure is realized. By using parameterized design software and form-finding analysis plug-in, reasonable structure shape and prestress distribution are found. At the same time, the key parameters of the basic structure system are analyzed, and the reasonable range of the key parameters is obtained. The analysis results show that the upper and lower radial cables of cable truss can be used catenary parabola and arc under the condition of control vector / span ratio. According to the analysis of building modeling and mechanical performance, it is suggested that the upper and lower radial cables of cable truss should be parabola in practical engineering. The reasonable range of rise-span ratio of radial cable is 1 / 40 / 1 / 20, that of lower radial cable is 1 / 40 / 1 / 30, that of internal concave radial cable truss is 32 / 44. The reasonable value range of the height difference ratio (c_1/c_2) of the outer ring and the upper ring is 1.0 ~ 1.5. In this range, the difference of the prestressing value of the upper and lower radial cables is less than 30%, and the distribution of the internal force of the structure is more uniform. The stiffness is better.
