In order to control the crack of the cantilever slab and decrease the moment of column, strandforce tendon is used in the slab and post cast strip is set during construction.

Influence of horizontal curvature of prestressing tendon in transverse beams on concrete cable-stayed bridge inclined web;

A study on construction of small curvature radius U prestressing tendon;

In view of the phenomenon that the tensioning elongation of sharp curvature radius tendons is slightly greater than the theoretic elongation, this paper analyzes the squeeze effect and strand effect that affect the tensioning elongation of the tendons, and proposes an uniform method for calculating the tensioning elongation.

Research on attrition loss of prestress wire with space curve

Through the test of friction loss of pipe with 6 kinds of prestressed reinforcement for 32m simply supported box girder of Yanmiao bridge of Wuhan-Guangzhou passenger special line,the least square method was used for the analysis,and friction coefficient between prestressed steel rope and pipe wall and pipe deviation coefficient were obtained.
