Optimising Electrochemical Remediation ForHistoric Steel Framed Structures

摘要: The problem of damage to historic steel framed structures as a result corrosion is now widely recognised in Western Europe, America and Australia. Structures built the late 19 or early 20 century are at greatest risk, together with earlier buildings that have received modifications structural interventions during this period. Traditional methods repair often too intrusive expensive consider. As consequence number important risk incurring extensive their stone faience finishes may require replacement new, non-original elements. Cathodic protection (CP) has been seen possible electrochemical solution frame use UK elsewhere for several years. In absence formal guidance standards, most installations rely on skill experience designers installers ensure effective remediation. To assist development such guidelines, Royal Society supported four year research programme into CP structures, carried out Centre Infrastructure Management Sheffield Hallam University. This paper describes completed study, its results conclusions shows how modelling processes helped identify key factors successful application technique achieve maximum minimum disruption original structure.
