Abstract: As a part of contexts for node design of cable dome, the anchor-hold of cable in cold pressure is investigated based on the experiment and finite element method. This work includes the mould machining, material choosing and the defining of the length of anchor. The research results indicate that if reasonable form of anchor in cold pressure is adopted, the anchor-hold can reach the design strength of cable.

Keywords: cable structure; node; anchor; cold pressure formed
