CONSTRUCTION PROCESS INVERSE SIMULATION ANALYSIS OF CABLE DOME BASED ON ANSYS

Based on the practical projects, adopting the nonlinear finite element method, the construction process of cable dome was analyzed.The integral lifting process of the structure was realized through changing the length of the cables and the temperature could simulate the variations of the cable length.Based on the ANSYS, the cable strut beam finite element model was established, and the positive constant force cables and the subsidiary cables, the passive cables and the mast were simulated with the two node curved element(link10 element), multistage link10 element, the link8 element and the beam4 element respectively.By the ANSYS powerful APDL programming function, the development program of cable dome structure construction process inverse simulation was made.Helpful reference was offered for the application of integral lifting in large-span cable dome.
