| Abstract: | The concreting of long span string beam is a new structure form, but the construction control of string beam is always a difficult problem in the construction field. In this paper, the key technologies in the construction process are studied, the accurate analysis model is established, the out-of-plane instability of the string beam is analyzed, and the displacement control and cable force control methods in the construction process are proposed. |
