Abstract

A load bearing assembly (20) includes a plurality of tension members (22). A joint in the load bearing assembly (20) has a staggered pattern of discontinuities (30) in the tension members (22). A stress relieving feature is associated with at least outermost tension members (22A, 22L) in the vicinity of the discontinuities. One example includes supplemental tension members (32, 50) as the stress relieving feature. Another example includes selected spacings (32′, 40, 42) between ends of at least some of the tension members. One example includes different sized tension members as the stress relieving feature. Another example includes different lateral spacings between selected tension members.
