Abstract

The present invention provides a method for configuring annular stiffening ribs of a steel tube tower, comprising: determining the ring plate thickness interval and the ring plate width interval according to the results of tests and finite element analysis; calculating the bending bearing capacity of node plates without stiffening ribs in different ring plate models in turn by fitting stiffening rib calculation formulas according to experiments based on the ring plate thickness interval and the ring plate width interval; calculating the price coefficient of each ring plate model; on the basis of meeting the bending bearing capacity requirements, taking the corresponding ring plate model when the price coefficient is the smallest as the configuration of the annular stiffening ribs of the steel tube tower; the ring plate model includes: various ring plate forms, ring plate thicknesses and ring plate widths. The method optimizes the calculation method of the ring plate stiffening ribs, makes full use of the strength of the material, and calculates the most economical ring plate stiffening rib configuration method through the steel weight index and price index, which can reduce the workload of manual calculation and selection and reduce the cost.
