| Popis: | 101 Taiwan was threatened by earthquakes and typhoons every year. Disasters of mountain rock falls occurred frequently. The first case of a simple cable was calculated with different computer programs for elastic analysis. The nonlinear ultimate load of the steel ring was studied. Then, the influences on axial force of the steel ring by modulus of elasticity, changes of ring diameter were discussed. According to the structural test example of steel wire net, the limit load analyses of ring-type wire net were carried out by different diameters of steel wire, material properties and geometric shapes. The analytical results were close to the experimental results of the cable net structure. The ultimate load and deformation analyses of steel wire net were studied with different assumed conditions. Those conditions included the elastic modulus, yielding stress, diameter of steel wire, transverse loading. Then, the load-deflection curves were found. Results of this research for steel wire net can be a reference used for the disaster prevention engineering. |
