Eight reinforced concrete specimens were fabricated and subjected to tensile membrane forces and air pressure to study the air leakage characteristics in cracked reinforced concrete members. A mathematical expression for the rate of pressurized air flowing through an idealized crack is presented. The mathematical expression is refined by using the experimental data to describe the air flow rate through any given crack pattern. Graphical charts are also presented for the calculation of the air…

Assessment of Gas Leakage Rates through Damaged Reinforced-Concrete Walls
AbstractThe increased permeability that develops in damaged concrete walls translates directly to increased leakage of gases through the wall. For reinforced concrete structures housing dangerous

The object of this paper is the prediction of the air flow through a cracked concrete wall element. Experimental data from permeability tests on large cracked reinforced concrete plates is used. The
Experimentally Measured Permeability of Uncracked and Cracked Concrete Components
In this paper, the relationship between concrete damage and air flow is evaluated using model-scale reinforced concrete walls. The focus is on the walls behavior under uniaxial and biaxial loading
Refined Modeling of Crack Tortuousness to Predict Pressurized Airflow Through Concrete Cracks
Cracks may appear in the pressurized concrete containment of a nuclear power plant during a severe accident and provide leak paths for release of radioactive aerosols dispersed in the contained air.
