摘　　要： 对大面积建筑中局部采用预应力的方法进行了深入分析 ,在工程中分别对预应力结构与周边普通钢筋混凝土结构的连接处采用了抗、放两种方式 ,取得了良好的效果。结合工程特点 ,采用了短跨为主梁、长跨为次梁的大跨度次梁结构 ,最大限度地控制了层高 ,同时满足地面层任意开孔的要求。 The method of prestressing locally used in large area building has been deeply analyzed in this paper. In practical engineering, two ways of resistance and loosening between the connection of prestressed components and RC structures, which is proved to be useful are adopted. Long span structure of junior beams where the short sides are used as girders and the long ones as junior beams has been utilized here according to the features of engineering, which can reduce the height maximally and meet the needs of holing on slabs freely.
