摘要
大直径圆形平板结构采用无粘结预应力技术 ,与矩形平板相比 ,其结构受力特点、布筋方式、设计计算有着不同的规律。采用双向条带“十”字配筋方式进行了预应力筋和非预应力筋布置 ,运用有限元法验算了等效荷载作用下圆板的变形 。
Using the technique of unbonded prestress in large diameter circular slab has different rule in contrast with rectangular slab in character of structure behavior,reinforcement distribution,design and calculation.Adopting bidirectional stripe cross reinforcement and finite element analysis under equivalent loads,the structural design of prestressed circular slab with large diameter is effectively solved.
