| Abstract: | The utilization of planished spiral bar as vertical presressing bar for concrete structure finds wide application in bridge structures.However,the problem is that the anchoring stress loss of the bar often can not be effectively controlled.In this paper,by way of several examples,the tests and construction of control of the stress loss are presented for reference to the construction of similar kind. |
