THE CONSTRUCTION TECHNOLOGY OF PRESTRESSED STEEL STRUCTURE FOR SIYANG STADIUM
-
摘要: 体育场位于江苏省泗阳县内,屋盖采用预应力斜拉结构。通过Midas/Gen软件分析得到设计张拉索力,并对施工过程进行仿真计算分析。介绍钢结构安装、预应力拉索安装及张拉等施工过程。根据工程特点,提出采用同一根柱子上前、后拉索同时张拉的施工方法,并对张拉过程中拉索索力、结构竖向变形等进行施工监测,结合施工仿真计算结果,提出监测结果的合理性和正确性,为钢结构和预应力施工方法提供依据。Abstract: The stadium was built in Siyang County of Jiangsu Province．The cable stayed gridding structure is used forthe stadium．The designed tensile force was gained from the calculation software of Midas/Gen．And the simulationcalculation was carried out in detail according to the construction course．The construction course of steel and cablewas introduced．According to character of this project, the construction methods of tensioning the front and backcables of the same pillar in the same time were provided．The cable force and the distortion were monitored in thecourse of construction．According to the construction simulation results, the rationality and correctness of constructionmonitoring were proposed．Which provided a basis for the methods of steel construction and prestressed construction．
