摘要
预应力钢结构施工的直接目标是张拉过程中实现设计要求的索力和结构形状,结合工程实际,介绍了高钒索施工工艺,若在对结构特点和施工过程的结构状态不十分了解的情况下张拉,可能会引起严重后果,故对预应力张拉及结构卸载等进行了分析,为类似工程提供借鉴。
The direct goal of the construction of prestressed steel structures is to achieve the required cable force and structural shape during the tensioning process.In combination with the actual engineering,the high vanadium cable construction process is introduced.If the structural characteristics and the structural state of the construction process are not well understood.In the case of tensioning,serious consequences may be caused.Therefore,prestressed tensioning and structural unloading are analyzed to provide reference for similar projects.
