In the construction project without construction joint design, it is proposed that using temperature variation effect and the creep shrinkage effect of the RC considers the difference temperature of control tape between construction stage and service stage. So we can count the RC temperature stress and deal with control tape, construction joint, and jump positions pouring.Keywords:over-length structure; temperature variation effect; creep shrinkage; control tape; construction joint; jump positions pouring.
