“…Different correlation lengths cause a difference in the results. However, in practice correlation lengths are often assumed based on literature and these assumed values for the correlation length of concrete properties are not consistent with each other [32]. The suggested values for the correlation length could be the initial values for further investigations.…”

“…Nonetheless, in most literature, the correlation length is assumed and these assumptions are not consistent with each other [32], the reason for this is the lack of available data [30,31]. The probability of failure can be underestimated resulting in an unconservative design if this value is ignored or implicitly assumed to be infinite [12,16,33,35].…”

“…In literature, different assumptions on the correlation models for corrosion variables can be found. Criel, Caspeele, & Taerwe (2014) summarize some correlation lengths commonly found in literature for corrosion and concrete variables, as presented in Table 1.…”

“…Concrete cover c 1 m -2 m -3.5 m (Li, Vrouwenvelder, Wijnants, & Walraven, 2004;Stewart & Mullard, 2007;Straub, 2011) Surface chloride concentration Cs 1 m -1.96 m -2 m -3.5 m (Duprat, 2007;Engelund, 1997;Straub, 2011;Vu, 2003) Concrete compressive strength fc 3.5 m (Duprat, 2007) The correlation models for the correlation coefficient ρ mentioned in (Criel et al, 2014) are the exponential correlation model (Equation ( 9)), the squared exponential model (Equation ( 10)) and the Matérn model (Equation ( 11)). The last one depends not only on the correlation length lc, but also on a smoothness parameter ν.…”

“…Variables often modelled by random fields are the concrete cover, surface chloride concentration, concrete compressive strength, critical chloride concentration, diffusion coefficient of the concrete, water/cement ratio, Young's modulus of the concrete, Poisson coefficient of the concrete, tensile strength of concrete, etc. (Vu & Stewart, 2005;Straub, 2011;Tran et al, 2012;Criel et al, 2014;Chen et al, 2018;Liang et al, 2022;Feng et al, 2022). There can be a large spread on the correlation lengths used for one variable, for example with ranges from 1 m to 3.5 m for the concrete cover and surface chloride concentration (Engelund, 1997;Vu, 2003;Li et al, 2004;Duprat, 2007;Stewart & Mullard, 2007).…”
