In this paper, the characteristics of natural frequency aquation of bending mould high-rise structures are studied, the iterative solution of natural frequeney is presented. This method overcomes the defect of the trial calculation mathod of graphic analysis,that its steps is overelaborate and reult is incorrect. And the exact result can be get quickly using the iterative solution.
Keywords: bending deformation; high-rise structures; vertical cantilever beam; natural frequency; iterative solution
