济南战役纪念馆拉索预应力网格结构设计

预应力网格结构是一种新型空间结构 ,它将预应力技术引入空间结构 ,拓展了预应力技术的应用范围。以济南战役纪念馆拉索预应力网格结构设计为背景 ,介绍了一种新型的拉索预应力网格结构布索方式———体内布索 ,即将预应力拉索视为网格结构的受拉杆件 ,与钢管拉杆组成组合构件 ,共同协调变形 ,达到既可提高结构承载力和刚度 ,同时又能更好地满足建筑美学功能及室内观瞻效果 ,提高索的防火、防腐能力

DESIGN OF STAY PRESTRESSED GRID STRUCTURE FOR JINAN CAMPAIGN MEMORIAL HALL

The prestressed grid structure is a new type of space structure,with which the prestress technique has been introduced into a space structure,thus widening the use scope of the prestress technique.According to the design of stay prestressed grid structure for Jinan Campaign Memorial Hall,the arrangement of the cables for this grid structure is introduced,where the prestressing cables are used as the tension members of the grid structure and formed composite members with steel tubular bars,which can regulate the deformations.Therefore,the load bearing capacity and stiffness of the structure are raised,and in the meantime,the capability of fireproof and anticorrosion of the cables are also improved.
