I did analysis of a pre-stressed wind turbine tower.I run the model for different strength of concrete, the change in the graph of bending moment vs and deflection was the slope of curve during the linear phase. and in the next case i kept the vertical axial force and the result was same with the vertical force in other 3 cases. the structure failed by compression at the front portion at about 2/3 height from the bottom.however, I could not achieve the horizontal line in BM vs deflection curve during the model like that of the experiment.the reinforced steel in compression region went under plastic phase
