ABSTRACT = {A new geometry design method of three-layered Seale wire strand is proposed. 
The included angle between adjacent helical wires in the same layer, which is 
assumed as zero in the conventional design method, can be predefined 
arbitrarily by using the new method. The key process of deriving the diameter 
ratio of each layer wires was formulated into a one-dimensional problem and 
golden section method was applied to solve the problem efficiently. Finite 
element analysis of the newly developed three-layered Seale strand was also 
implemented by using a concise finite element model (FEM) which takes full 
advantage of the helical symmetry and cyclic symmetry of the three-layered 
Seale strand analysed in this paper. Three-dimensional solid brick elements 
were used for structural discretization. Nonlinear factors such as inter-wire 
contact and material plasticity were also taken into account. Numerical results 
show that the circumferential angle of helical wires is very small for the threelayered Seale strand subjected to axial tensile loads. For the 19-wire Seale 
strand loaded in the linear region, when included angle is predefined beyond 
0.0042°, it can be ensured that the helical wires in the same layer will not touch 
each other.},
