Comparative Design Aspects of Reinforced Concrete Liquid Retaining Structures

Reinforced concrete water retaining structures (RCWRS) must be designed so that the facility to be safe from leakage. One of the determining factors for the design of RCWRS is design with restriction of cracks. According to EN 1992-3 are defined four tightness classes in order to show degree of protection against leakage. In general, design of RCWRS can be done in two main cases: design without cracks and design with induced cracks which are controlled one. In this paper is shown the case where in design are foreseen to apply the concept of controlled cracks by application of joint tube for induction of cracks which takes rheological effects of concrete. The rheological effects of concrete can cause cracks which on one side are very difficult to predict where they will appear, while on the other side the appearance of these cracks greatly affects the degradation of the structure
