Introduction The heat(cold) caused by atmospheric temperature may make concrete heat(cold) in the process of pile of raw materials, transportation, into the mold, liquidated, maintenance[1] [2],thus changing the placing temperature of concrete, as a result, the temperature field and the temperature stress of concrete are changed.
Namely, don't consider properties of these materials changes as time. 5) Select the appropriate unit on the basis of different elements type provided by ANSYS.
