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.

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 ...

Diagonal crack width towards the experimental results
Budownictwo i Architektura, 2013 The results of research on diagonal crack width in a single span RC beams were presented in the article. Eurocode 2 rules do not require the direct control of shear crack width.

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.

Analysis of Crack Width Development in Reinforced Concrete Beams. [PDF]
Materials (Basel), 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 ...

Crack widths close the reinforcement [PDF]
IABSE Reports, 2007 <p>Currently used design methods predict that the crack widths at the concrete surface increase significantly with concrete cover. Requirements concerning limitation of crack widths therefore makes it difficult to use large concrete covers, which otherwise is desirable to reduce the corrosion of reinforcement.

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 ...

Cracking assessment in concrete structures by distributed optical fiber [PDF]
, 2015 In this paper, a method to obtain crack initiation, location and width in concrete structures subjected to bending and instrumented with an optical backscattered reflectometer (OBR) system is proposed.

Probability-Based Crack Width Estimation Model for Flexural Members of Underground RC Box Culverts
Applied Sciences, 2022 Crack control for slabs and beams in current design practices in Korea are based on the Frosch’s model, which is adapted in ACI 318. It is more difficult to have consistent quality control in underground construction sites, such as the RC box culverts ...
