Abstract:
      In this paper,a simple method on the plastic limit analysis of annular plates under linearly load has been given out. It is singular function method . With this method, the limit loads of annular plates at outside or inside boundary supporting have been calculated in this paper. The influence curve which shows the effect of the geometric parameter on limit load was traced. The computational results obtained in this paper are reasonable and with considerable regularity.
