## Abstract

A segment for an annular structure is disclosed. The segment includes an arcuate body extending between a first end and a second end. The segment includes a first plurality of interlocking portions extending from the first end and a second plurality of interlocking portions extending from the second end. Each interlocking portion includes a first leg and a second leg partially embedded in the arcuate body and a connecting portion connecting the first leg and the second leg, the connecting portion external to the arcuate body. The segment also includes a flange proximal to the first end and the second end of the arcuate body. Each flange includes a first spacing portion that extends radially outward from the outside surface and a second extending portion that extends distally from the main body portion.

## Claims

### Claim at position 1

1-14. (canceled)

### Claim 15

A method for forming a joint between adjacent segments in an annular structure such that the joint transfers moments and shear forces between adjacent segments, the method comprising:
overlapping interlocking portions extending from a free ends of a first segment with interlocking portions extending from a second segment; and
casting a field closure over the overlapping interlocking portions.

### Claim 16 (depends on 15)

The method of claim 15, further comprising:
inserting a support member into the overlap between the interlocking portions.

### Claim 17 (depends on 16)

The method of claim 16, wherein the support member comprises rebar.

### Claim 18 (depends on 16)

The method of claim 16, wherein the field closure comprises cement or concrete.

### Claim 19 (depends on 16)

The method of claim 16, wherein casting the field closure comprises casting the field closure from an interior side of the annular structure.

### Claim 20 (depends on 16)

The method of claim 16, further comprising positioning a first segment relative to a second segment to form a section of the annular structure.
