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 ...

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 ...

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 ...

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 weak magnetic nondestructive testing for cracks in the top beam of hydraulic support
Gong-kuang zidonghua, 2022 In view of the complicated operation of the current crack detection method of hydraulic support, a weak magnetic nondestructive detection method for cracks in the top beam of hydraulic support based on geomagnetic field excitation is proposed.

An Adaptive Crack Width Prediction for Flexural Steel Reinforced UHPC Beams
International Journal of Concrete Structures and Materials, 2023 The crack pattern of steel reinforced ultrahigh performance concrete (UHPC) beam is usually characterized by many densely distributed fine cracks (i.e., multiple microcracks) along with localized macrocrack, and the crack width development rate along the
