Hi Jim 0216, that's why I included txt in the post "(excluding the bridge Cable anchoring)". i.e. the anchoring in concrete. I believe your original question was regarding a "tensile" loss in the "suspending" steel of the bridge (over time) verses Oroville Spillway Radial Gate Anchor Tendons.

Yes the main suspension cable is anchored in concrete. The cable is split into many subsection termination points to distribute the stress loading and facilitate the termination technique in the concrete. Even in the concrete the bridge cable maintains its "tensile" stress from the "pull" of the suspension bridge. For longevity the anchoring of the steel cable bundles in the concrete must have superior corrosion protection & maintenance. Below is a cross section piece of one of the dual main suspension cables.

Thanks.

Have you ever visited the GGBridge? The cable shown is on the SF side of the walk you can take across the bridge. On a warm day in SF - not a frequent occurrence - it is a delightful walk.
