Reference number : GC-2017-Q3-00532, amendment number : , agreement type : G, recipient legal name : Lachemi, Mohamed (Ryerson University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : One of the key issues in the design of concrete liquid containing structures (CLCS) is their cracking_x000D_
characteristics and its relation to the liquid leakage. A consistent knowledge on this matter is essential to ensure_x000D_
if the serviceability requirements are met. The previous research conducted in this area is very limited. Most of_x000D_
the available literature is focused on the leakage behavior of typical beam sections made of normal concrete_x000D_
under simple static loading. The lack of empirical data on the permeability behavior of slab or wall sections_x000D_
made of smart material under combinations of loadings is felt in the literature. This study intends to address_x000D_
this issue both analytically, using the non-linear finite element (FE) analysis and experimentally, measuring the_x000D_
leakage rate in the loaded specimens under pressurized water as a function of the crack conditions and time._x000D_
The issue is of particular significance for CLCS used in lifeline facility capacities such as in municipal water_x000D_
supply, sewage treatment, firefighting, nuclear industry, etc. In such applications, due to functionality reasons,_x000D_
crack and leakage control is the main concern and an uncontrolled cracking could lead to irreparable_x000D_
consequences. The major issue to be emphasized in this research is the development of cracks leading to_x000D_
uncontrollable leakage in the vulnerable regions of the containment walls due to different loading applications_x000D_
including seismic. Current design codes do not address this issue adequately and it is left to design engineers to_x000D_
conservatively consider it in their design, thus necessitating a more detailed and focused investigation. The_x000D_
main objective of this research is to assess and compare the performance of self-healing ECC (Engineered_x000D_
Cementitious Composites) and normal concrete material in controlling the crack/leakage in CLCS in an effort_x000D_
to achieve the most desired water tightness characteristics in this type of structures. In this relation, it is_x000D_
proposed that various loading types and stress combinations be induced in specimens representing a reinforced_x000D_
container wall and their water-tightness behavior be examined then., program purpose french : One of the key issues in the design of concrete liquid containing structures (CLCS) is their cracking_x000D_
