“…Therefore, the corrosion depth was assumed to follow the normal distribution in this paper, and the probability distribution of corrosion depth was tested. The mean and standard deviation of the normal probability model of corrosion depth through linear regression (Nie et al , 2019). The test process for the probability distribution of corrosion depth was as follows:…”

Purpose This paper aims to investigate the evolution law of surface characteristic of corroded cold-formed thin-walled steel in industrial environments. Design/methodology/approach Five test specimens sourced from cold-formed thin-walled C-shaped steel that have been in service for three years in actual industrial environments were subjected to surface characteristic test. The surface characteristic of corroded hot-rolled steel and cold-formed steel were compared and analyzed. The relationship between the surface morphology parameters and the average corrosion depth was established. Findings The evolution law of the surface morphology of corroded cold-formed thin-walled steel and corroded hot-rolled steel was similar. The frequency histogram of corrosion depth was mainly single peak with high values on the middle and low values on both sides. The corrosion depth conformed to the normal distribution. The roughness average height and the root mean square of surface height gradually increased linearly with increasing the average corrosion depth. Originality/value The reduction in the standard deviation of corrosion depth, the maximum corrosion depth, the roughness average height and the root mean square of surface height of the cold-formed thin-walled steel was smaller than those of the hot-rolled steel.

“…It includes the stochastic variability of loads, soil properties, geometry, and corrosion processes. This index can be exploited to evaluate the appropriate inspection frequency, considering that the structure is under continuous degradation (i.e., strength loss due to corrosion of steel) (Nie et al, 2020).…”

The construction industry plays a critical role in tackling the challenges of climate change, carbon emissions, and resource consumption. To achieve a low-emission built environment, urgent action is required to reduce the carbon emissions associated with steel production and construction processes. Reusing structural steel elements could make a significant impact in this direction, but there are five key challenges to overcome: limited material availability, maximizing different reusable materials from demolition, lack of adequate design rules and standards, high upfront costs and overlooked carbon impact of the demolition prior to construction, and the need to engage and coordinate the complete construction ecosystem. This article described these barriers and proposed solutions to them by leveraging the digital technologies and artificial intelligence. The proposed solutions aim to promote reuse practices, facilitate the development of certification and regulation for reuse, and minimize the environmental impact of steel construction. The solutions explored here can also be extended to other construction materials.
