| Abstract: | A finite analysis calculation method of the internal force and displacement on the wire rope structure is presented.The wire rope is divided into a series of discretional units,and the equations of the balance and displacement in those units are constituted.With the confined condition on the top of the wire rope and the connected condition on the internal force and displacement between those units,the transfer matrix of the original parameter is computed and evolved as well as the numerical value.By the method of gradual approach,the computer software is developed for the calculation of the numerical value.Finally,two applied examples of the wire rope structure are introduced. |
