Abstract

Abstract

Cracking of concrete caused by early age volume changes such as shrinkage and thermal deformati on is always a problem for cast-in-place concrete structures. Such premature cracki ng affects the serviceability, durability, and even safety of the concrete structure. Integrated analysis is preformed for deformation-caused cracking from the aspects of materials, structures and constructions. Based on the bond-slip theory, cracki ng mechanism and parameters are analyzed and calculated for the axial restrained reinforced concrete members, and finally the differences in mechanical properties between load-caused and deformation-caused crackings are compared.
