Abstract:
In order to solve the the problem of the difficulty of recognizing the internal force of a short suspender,the idea of an equivalent length is introduced with different boundary conditions of a short suspender.In view of the suspender,series of simulation data are used and the relationship between the equivalent length and dimensionless parameters ξ are obtained.The method of recognizing the internal force of a short suspender considers the influences of bending rigidity.The method here provides a meaningful exploration on recognizing the internal force of a short suspender.
