A joint structure, such as a bulkhead (22) joined to an annular shell (20), is formed by providing a conformed pattern of ridges (30, 32 & 38) and valleys (39a & 39b) on the facing portions of the elements to be joined. A tensioned band (46) is applied to the external surface of the annular shell (20) overlying one of the ridges in the annular shell (20). The tensioned band (46) stresses the joint in compression, offsetting subsequently applied shear stress so as to negate peeling failure forces. The joint loadings are sustained with a mechanical interlocking, making the use of an adhesive optional.
