In this paper,Four unbonded partially prestresse d high strength concrete beams were tested and studied,At the same time,one unbo nded partially prestressed high strength concrete beam under long\|term load was tested and studied.Warping character under the concentrated load was explored.T hrough analyzing and ascertaining, it was put forward that check method of norma l use ultimate state based on joining with code GBJ10-89 in China,which provides reference and use for revising high strength concrete code and designing engineering.
