Abstract:
In response to the need for a single-layer hyperbolic cable net structure for a stadium, the wheel-spoke scheme and the loop-free scheme were proposed. Based on the shape, design of components and connections, economic indicators including the consumption amounts of cables, cable end anchors, and large-scale cable clamps were compared. Based on FEA software Midas / Gen, the displacement and cable force under static load were analyzed, and the structural stiffness, cable force and cable force distribution uniformity of both schemes were discussed. Using FEA software Ansys / Ls-dyna, the component removal method was adopt to analyze the dynamic response after the cable rupture, and progressive collapse resistance of both schemes were discussed. The results show that the loop-free scheme has advantages in economy, with the consumption amounts of cables, cable end anchors and large-scale cable clamps significantly less than those of the wheel-spoke scheme. The loop-free scheme has better rigidity, good integrity, smaller cable force and more uniform cable force distribution. The loop-free scheme still maintains the stable shape after the cable rupture, with insignificant cable tension loss and better progressive collapse resistance. © 2022 Science Press.
