Deformation of Overlong Isolated Buildings Caused by Thermal and Concrete Shrinkage

Table 5

Distance of expansion joints for isolated building.

Building’s heating and thermal insulation condition	Temperature difference (°C)	Distance of expansion joints (m)
Indoor heating	7~12	80~140
Indoor without heating but wall with exterior insulation	20~25	40~50
Open air	25~35	30~40
