摘　　要：利用SAP93软件,根据某高层结构预应力混凝土转换厚板的正常使用极限状态,用等效荷载法确定了预应力钢筋的数量和布置方式;由承载力极限状态得到非预应力筋的大小,采用必要的外加剂保证厚板的施工质量,预应力钢筋的张力大小用双控法确定。在结构的施工过程中,对转换板的受力性能进行了检测,测量值与计算值相符。The number and layout of the prestressed reinforcement are calculated using the equivalent load method according to the normal use limited state of the transferring thick plate.The SAP93 software is used.The amount of the common reinforcement is decided based on the bearing capacity limited state.Necessary aruhuesirus are used in order to ensure the construction quality,and the tensile forces are determined by the bi-controlling method.The carrying performance of the plate is detected in the construction process,and the results meet the calculation values.
