Structural design knowledge: Prestressed steel anchor node which design requirements?

     What prestressed steel anchor node design requirements?
     A structure based on the actual situation, should take pre-afterburner design value of 1.2 to 1.5 times the tendons (cable) design values of internal forces;
     Two pairs of important and complex node should Capacity Test conducted full-scale or scale model, the actual stress state of load cases node model tests should be consistent with the node;
     3 anchor node area should stress analysis and connected computing, and should take credible structural measures; node area should avoid overlapping weld, cut, etc; structural, mechanical complex node can be cast steel nodes.
