摘要
包头市东海商厦主体框架梁采用有粘结预应力技术,预应力张拉过程中采用了应力控制、伸长值校核的双控措施。文中介绍了该项技术的施工工艺及曲线有粘结预应力筋理论张拉伸长值的计算。
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.
