Numerical Simulation and Test Study on Non-uniform Area Of Round-ended CFST Tubular Tower

摘要：

The impacts of Poisson ratio of core concrete on the bearing capacity of round-ended CFST tubular tower and non-uniform area were analyzed with test study and the sub-model technology, the most disadvantaged stress state of the structure under the triaxial compression was also studied. The results indicates that: with the variable concrete Poisson ratio, comparatively, the bearing capacity analysis considering the variable concrete Poisson ratio enables to enhance the design capacity, sub-model method was used to analyze the non-uniform area, the results reflected the change rules of stress of round-ended CFST tubular tower in axial compression case and eccentric compression case, in addition, the most disadvantaged stress state of the structure under the triaxial compression was found out.
