钢筋混凝土构件非受力裂缝浅析

Preliminary analysis about the causes of non-structural cracks in reinforced concrete members

钢筋混凝土构件裂缝往往被认为是由于地基不均匀沉降或构件承载力不足造成的 ,然而在民用住宅中大量的、常见的裂缝却是因构件自身的收缩、环境温度变化等原因引起的 ,对此种裂缝 ,即“非受力裂缝”

The causes of cracks in reinforced concrete members are often considered as unequal settlement of foundation bed or insufficient bearing capacity,but in fact the cracks which are commonly seen in residential building are non-structural cracks,always because of shrink、the change of environmental temperature etc.;in the paper,the causes of such cracks are discussed.
