The steel embedded in pre-stressed concrete structure will be pretensioned prior to load application and thus made to pre-stress the concrete so as to offset or reduce the tensile stress produced by loading, then to improve the crack resistance and rigidity of structural members accordingly as well as to reduce the width of crack and use the high-strength steel and concrete in an effective way and so then save steel and cut down dead weight.
The steel wire or cable is made,Friction losses small,No secondary grouting,Construction is more convenient Used for:Big span reinforced concrete structure,Anchorage foundation.
