Crack width for thick offshore plates
Materials and Structures, 2011Using thick concrete covers in offshore and nuclear containment applications is increasing because it is a durability issue. Most crack width models indicate that increasing concrete covers results in increased crack spacing and hence increased crack width this means that thick concrete covers are detrimental to crack control. In this paper, tests were

Crack spacing and crack width investigation from experimental CRCP sections
International Journal of Pavement Engineering, 2006Crack width (CW) and crack spacing (CS) data from full-scale continuously reinforced concrete pavement (CRCP) test sections were collected and analyzed for this study. In order to compare CWs obtained under different temperature conditions, the CRCP CW model presented in the new mechanistic–empirical pavement design guide (MEPDG) was utilized to ...

Crack Width Evaluation of Reinforced Concrete Membrane Elements
Structural Engineering International, 2009The design methods developed over the last few decades to describe the behaviour of two-dimensional reinforced concrete elements subjected to in-plane loading do not permit a simplified assessment of crack opening: some of these methods, in fact, permit this assessment but are difficult to use for practical design purposes, whereas others, instead, can

Uncertainties of Crack Width Models
2017Crack widths for verification of serviceability limit states can be calculated by simplified formulas provided by codes of practice or by numerical analysis based on nonlinear finite element methods. Authors performed a pilot study with the aim to develop a methodology for assessment of model uncertainty involved in the crack width analysis ...

Cracking and Crack Width Patterns in Large Masonry Beams
ACI Structural Journal, 2014Earlier studies on large reinforced concrete (RC) beams found that the width of side-face cracks can be larger than the width of cracks at the extreme tension face. Accordingly, many RC design standards and codes recommend using skin reinforcement to limit the width of side-face cracks.

Crack space and crack width of weldmesh ferrocement under cyclic loading
Cement and Concrete Composites, 1994Abstract As part of a large programme, a study of crack width under cyclic loading has been carried out. The crack space, which is thought to be one of the most important factors influencing crack width, has received special attention. Test results and theoretical studies show that the cracks in the ferrocement tested have an insignificant influence ...

Determination of crack spacing and crack width in reinforced concrete beams
Structural Engineering and Mechanics, 2003In this paper spacing and width of flexural cracks in reinforced concrete beams are determined using two-dimensional finite element analysis. At early loading stages on the beam the primary crack spacing is based on the slip length, which is the development length required to resist the steel stress increment that occurs at a cracked section on the ...
