［摘要］檢察官學院體育中心網(wǎng)球館屋蓋采用雙向張弦梁結(jié)構，它屬于半剛性結(jié)構，張拉前的整體剛度很小，施工過程中會產(chǎn)生較大的變形，結(jié)構的預應力和索力控制難度大，這給施工帶來了許多困難。通過施工仿真模擬，研究了不同張拉級別和張拉順序?qū)Y(jié)構的影響，確定了實際張拉工序，在實際施工過程中采用多種索力監(jiān)測方法確保拉索的精確張拉。實踐證明，施工中采取的張拉順序和張拉級別能夠保證施工質(zhì)量；施工仿真模擬與實測數(shù)據(jù)吻合較好，對同類工程具指導意義。

Abstract:The roof of tennis hall of sports center of National Prosecutors College adopts bidirectional beam string structure, which belongs to semi-rigid structure. The overall stiffness before tension is very small, and there is large deformation in the construction process. It is difficult to control the prestress and cable force of the structure, which brings many difficulties to the construction. Through construction simulation, the influences of different tension levels and tension sequence on the structure were studied, and the actual tension process was determined. In the actual construction process, various cable tension monitoring methods were adopted to ensure the accurate tension of cables. Practice has proved that the construction quality can be guaranteed by the tension sequence and tension level adopted in the construction and the simulation of construction is in good agreement with the measured data, which has guiding significance for similar projects.
Keywords:bidirectional beam string structure; construction simulation; prestress; tension control; nonlinear analysis
