| Abstract: | The main framework of the Donghai Commerical Building in Baotou was used bonding prestress technology. It was taken the double - control measures of controlling stress and checking the elongation value in the pretressed tensioning process. The paper introduces the construction technology and the calculation method of the theoretical elongation value of the bent bonding prestress bars. |
| Keywords: | bonding prestress steel strand construction technology |
