摘要
近年我国许多采用部分预应力混凝土框架结构的超大建筑物 ,不设或少设伸缩缝 ,若不采取措施 ,将出现大面积开裂 ,由于结构的温度应力与混凝土收缩、徐变有直接关系 ,因此分析的难度很大。对此采用一套以弹性有限元分析为基础的方法 ,对大面积混凝土梁板结构温度应力进行分析 ,可为超大建筑物的设计提供依据。
In recent years many extra huge building adopt part-prestressed concrete frame structure in China,in which no or less expansion joints were made.If no technical measure shall be taken large area cracks may occur.As there are direct relationship between temperature stress and shrinkage / creep of structure concrete,the analysis of these structure is very difficult.Adopting elastic finite element analysis method to analyze temperature stress in large area concrete beam-slab structure may provide basis for extra huge building design.
