![]() ![]() ![]() This issue regarding the mechanics of concrete structures has been presented on the basis of calculation models since 1968. This research paper presents and comments on analytical models for calculating the widths of cracks formed as a result of imposed deformations generating tensile stresses in reinforced concrete base-restrained members. ![]() K E Y W O R D S crack control, crack width, leak-tightness, standards, thermal and shrinkage cracking This work resonates with the scope of the RILEM TC 287-CCS: Early age and long-term crack width analysis in RC structures. This work is a state-of-the-art review of the methods for crack width control due to imposed strains recommended by different regulatory documents from Europe, USA, Australia and Japan, and provide a reasonable degree of guidance with respect to the assumptions, possibilities and restrictions of each method. For these reasons, several standardized methods exist throughout the global engineering community which encompass differences between them. ![]() Crack control throughout the service life of a structure has always been a challenging task for engineers and asset owners, particularly those who are involved with the design and construction of structures with increased durability requirements, such as liquid retaining structures, nuclear containment buildings or structures in direct contact with ground, but also other externally restrained structures. ![]()
