Abstract:The photoelectric tower in Suqian Development Zone Photoelectric Center adopts staggered grid tube-in-tube steel structural system, and the pile foundation is adopted. The epidermal form of the tower is complex irregular surface and the tower locates at high seismic intensity area with large wind load, so the design difficulties include the structural spatial layout determination, complex structure design and connection joint design. The structural system of the tower was introduced as well as the member section form and design goals. Based on programs of MIDAS Gen and YJK, the upper structure was calculated to ensure the reliability of the analysis results. During the calculation, not only the dead load, live load, wind load and earthquake action were considered, but  also the thermal action was  taken into account, and the overall stability of the structure was also analyzed. The mechanical properties of typical complex joint, and the joint design and its corresponding construction drawing generated based on CATIA secondary development technology were also introduced preliminarily. The calculated results show that the design goals meet the requirements of the codes.

Keywords:photoelectric tower; staggered grid tube-in-tube; structural layout; thermal action; overall stability; joint analysis; secondary development technology
