Abstract

By the no-joint design of a 103 m long sickroom building,it is analyzed the tensile stress caused by concrete shrinkage and temperature decreasing,also put forward a series of techniques to control the cracks.Post-poured strip was used to enhance the prestressing effect of steel bars.It is verified the distribution regularity of temperature stress and shrinkage stress and effectiveness of the above techniques by stress detecting during and after construction.
