Test Study on the Influence of Periodical Temperature Stress on the Loss of Structural Prestress

Abstract:

In order to study the prestress loss of the periodical temperature stress on the structure, this test has carried out the temperature stress analysis of 4-piece prestressed rectangular columns. The test takes Baiguodu Bridge in Chongqing Municipality as the supporting engineering to simulate the continuous effect of annual temperature change, for the measurement of prestress loss of the concrete structure. The study has shown that: prestress loss from periodical temperature change exists, and in the present, the design has insufficient estimation on this loss.
