“…Research on tightness of concrete generally concludes that through‐cracks are required to achieve mention‐worthy leakages, which is aligned with Beeby's view from 1978 . It is noted that some of the research groups seem to have tested either unreinforced concrete discs, or a small portion of the structural member, for example, the tensile zone of a beam under flexural loading . Both cases represent through‐cracks, and are further used as basis for recommendations on a more general basis.…”

“…Both cases represent through‐cracks, and are further used as basis for recommendations on a more general basis. Desmettre and Charron tested an RC‐tie, and concluded for flexural cases based on the through‐cracked results. Ziari and Kianoush tested pure tension elements and explicitly limited the relevance of the findings to pure tension load situations with through‐cracks.…”

This paper includes a critical review of the literature related to design of reinforced concrete structures in the serviceability limit state (SLS), and attempts to tie the results to code requirements. The main attention is given to the so‐called controllable cracks, defined as cracks due to imposed loads or deformations on hardened concrete or restrained volume changes in young hardening concrete that a structural engineer has the knowledge and tools to predict and control. It is suggested that more consistent procedures are introduced into the future SLS‐design. It is found necessary to more clearly distinguish the crack width requirements for aesthetic reasons from durability and tightness reasons, and clarify the use of the term durability in the code text. The research leading up to current leakage prediction formulas and tightness formulas is questioned based on the literature review. It is discussed that a differentiation of the crack width through a cross section will facilitate a more consistent treatment and limitation of crack widths.

“…The multiscale framework we present here is suitable for mass transfers within concrete structures or their components. To that aim, we focus on experimental results from Desmettre and Charron who designed a coupled tensile—permeability test on RC specimens ( 610 × 90 × 90 mm 3 concrete element including a 11 mm diameter reinforcement bar). Here, we aim at comparing their experimental measures to numerical results and focus on the permeability evaluation along the failure process.…”

International audienceA two-scales numerical analysis is set up in order to upscale the permeability of fractured materials such as concrete. To that aim, we couple finite element (FE) kinematics enhancements (strong discontinuities) representing fine scale cracks to the fine scale permeability tensor. The latter may be split into two parts: the first one is isotropic and corresponds to flows within the porosity of the material; the second one, based upon a set of cracks with different orientations and openings, is anisotropic. For the latter, each crack is a path for mass flow according to the Poiseuille law considering two infinite planes. We show how the upscaling procedure leads both to the definition of macroscopic permeability tensors as well as the flow rate evaluation for components of concrete structur

The durability of concrete structures strongly depends on the water and chloride penetration in cracked concrete during its service life. This work aims at modeling the damage effect of tension stiffening behavior on the permeability for concrete tie specimen under tensile load by a dual lattice model, which considers hydromechanical couplings. Three concrete materials, including normal strength concrete (NSC), steel fiber reinforced concretes (SFRC), and ultra high‐performance fiber reinforced concrete (UHPFRC), are considered. The hydromechanical lattice model is based on a dual element network modeling: the water transport and the mechanical response. The fiber bridging effect is considered by means of the cohesive law of Mazars. The water flow in the damaged conduit elements is proportional to the cube of the crack width, which results from the damage variable. Experimental results available in open literature for both NSC and SFRC tie specimens are used to analyze and validate the proposed model. Considering a UHPFRC tie specimen, the model well predicted the load drops due to macrocrack occurrence, load hardening, and permeability evolution. Based on the present results, the current lattice hydromechanical model is a useful tool for predicting the service life of steel bar reinforcing concrete structure with and without steel fiber reinforcement.
