Probabilistic Analysis of Crack Width
Acta Polytechnica, 2000 Probabilistic analysis of crack width of a reinforced concrete element is based on the formulas accepted in Eurocode 2 and European Model Code 90. Obtained values of reliability index b seem to be satisfactory for the reinforced concrete slab that ...

Image-Based Crack Detection Using Crack Width Transform (CWT) Algorithm
IEEE Access, 2018 This paper describes an image-based methodology for the detection of structural cracks in concrete. The conventional approach based on line enhancement filtering has problems associated with an inaccurate extraction of edge pixels.

Analysis of Crack Width Development in Reinforced Concrete Beams [PDF]
Materials, 2021 The reliability and durability of reinforced concrete structures depend on the amount of concrete cracking. The risk associated with cracks generates a need for diagnostic methods for the evaluation of reinforced concrete structures. This paper presents the results of a study of 10 single-span reinforced concrete beams to follow the process of crack ...

Experimental Study on the Correlation between Crack Width and Crack Depth of RC Beams [PDF]
Materials, 2021 The depth of cracks propagating inside reinforcement concrete (RC) components is barely able to be detected by visual inspection. Without any help from facilities, crack width can provide us with a proper way to explore the depth of cracks developing.

Flexural behaviour of ferrocement. [PDF]
, 1982 Ferrocement is often believed to be a form of reinforced concrete. However, in spite of the similarities between the two materials there are still major differences, indicating that ferrocement requires a separate study to establish its structural ...

Crack Width Evaluation of Cracked Mortar Specimen Using Gas Diffusion Characteristics. [PDF]
Materials (Basel), 2023 Several methods have been proposed currently for evaluating the crack width of a mortar specimen. Among these, the water permeability test is widely used to estimate crack width because water permeability is directly related to the average crack width of a specimen through which water passes.

Crack width and crack spacing in reinforced and prestressed concrete elements: Data description and acquisition. [PDF]
Data Brief, 2023 Existing databases containing measurements of crack width and spacing are usually limited in size and based on isolated experimental studies. These databases are used to develop new formulas to describe crack patterns in concrete structures. A database obtained from multiple sources of experimental programmes is required to quantify the accuracy of ...

Corrosion Fatigue Crack Propagation Behaviour of a High Strength Low Alloy Steel in a Synthetic Sea Water Environment. [PDF]
, 1986 The corrosion fatigue crack propagation behaviour of a high strength low alloy steel, N-A-XTRA 70, in a synthetic sea water solution was tested using S. E. N. specimens subjected to a loading frequency of 0.1 Hz and a load ratio of 0.6.
