Abstract

Post-poured strips are often placed to release most of the shrinkage strain for concrete floor structures.The distance between post-poured strips depends on stiffness of supporting structures,shrinkage value and closure time.The later is the closure time,the smaller is the continuous bar area and the greater the width is,the smaller the restraining tensile force in bars of post-poured strip will be.It is advantageous to realize the function of post-poured strip and strengthen its crack resistance.
