| Abstract: |
| Three-dimensional finite element models are developed by using the general-purpose finite element software ANSYS, to simulate and analyze the static behavior of single-layer plane cable net with different damages, including failure of connectors between horizontal cables and vertical cables, the cable prestress loss, failure of the cable anchor end, and the corresponding tests are carried out to validate the finite element model. The results indicate that this finite element model is able to accurately analyze the influence of the above-mentioned three damages on the static behavior of the single-layer plane cable net, including the structural deformation and the distribution of cable forces. And this finite element model can also accurately take into account the effect of the location and extent of each damage, correctly reflect the situation of the structural damages. Hence it can be applied for further finite element parametric analysis on the single-layer plane cable net with different damage characteristics and structural characteristics, based on which the reliable structural safety analysis model and method can be established. |
