Abstract:
Relation between the changes of cable forces of centrosymmetric spoke structures and the deviation of cable's length was achieved; based on the reliability theory, a method for controlling deviation in cable's length was proposed by limiting the first-order-second-moment reliability index; and criteria of control deviation in cable's length were made for spoke structural roof of Bao'an Stadium of Shenzhen. The study results show that this method can offer standards for producing cables of spoke structures, and can assure the accuracy of cable forces at the initial prestress state. Deviation control of cable's length in manufacturing process is significant to the construction process of spoke structure designed and tensioned in fixed size and length.
