Abstract

The concrete section of one prefabricated steel-concrete wind turbine tower is usually fabricated segmentally in the factory and assembled on site by means of circumferential dry connection between segments. In this paper

according to the structural characteristics of circumferential joints between segments

the torsional load capacity of the circumferential joints between concrete segments under the interaction of vertical force and bending moment is derived as one integral expression and calculated by Python programming. The accuracy of the theoretical integral equation and the Python program is verified by comparing the results of two sets of ABAQUS refined finite element simulation with the published test results of the torsional load capacity for the circumferential joints between aluminum tubes. Finally

the torsional load capacities of 15 concrete segment cases with typical sizes and vertical forces are carried out by the proposed method. A 6-parameter model predicting the torsional load bearing capacity of the circumferential joints is proposed

and the values of these parameters are determined by least squares method. The design formula is proposed for the torsional load bearing capacity of the circumferential joints between concrete segments in prefabricated steel-concrete wind turbine towers.
