This research is focused on modeling the damage of concrete due to corrosion. The load used in this paper is only focused on the internal load due to rust expansion. In this study, corrosion was modeled uniformly and non-uniformly to investigate the difference between these two configurations to the damage in concrete. The simulation in this study was carried out using the 3DNLFEA program. The results show that numerical simulation provides predictions that are in line with experimental and numerical modeling results performed by the previous study in terms of pressure and corrosion cracking patterns. From the crack analysis, the pattern found that a non-uniform corrosion model can be used to express a realistic rust corrosion development around the reinforcement. Meanwhile, uniform corrosion requires a larger loss of steel area to reach the damage stage. Therefore, for non-uniform corrosion, the corrosion rate cause cracks and reaches a limiting crack width at earlier times in the service life of the corroded part.

“…For a long time, the steel reinforcement in concrete is assumed to be uniformly corroded, partly for simplicity of analysis [1,2]. However, it has been gradually accepted that non-uniform corrosion is the most common case of naturally corroded steel reinforcement in concrete structures in chloride-bearing environments [3,4]. The non-uniformity of corrosion along the steel reinforcement is more detrimental to the performance of concrete structures than the case of uniform corrosion [5,6].…”

In this work, the non-uniform corrosion characteristics of steel bars in stressed reinforced concrete beams after accelerated depassivation and seven-year outdoor natural corrosion is analyzed using fractal theory. 3D laser scanning and 3D reconstruction technology are applied to collect the cross-sectional area along the steel bars and obtain the corrosion curves. The non-uniformity of corrosion is analyzed by fractal dimensions which is calculated by variation method. The results indicate that the initial loading level and loading zone have some influence on non-uniform characteristics of steel bars. For an ordinary concrete beam, the increase of load can cause a reduction of fractal dimension of corrosion curves by 5%, which indicates the non-uniformity of corrosion will increase with the increase of load level. The fractal dimension in the bending zone is lower than that in the tension–shear zone, which indicates that corrosion is more non-uniform in bending zone. However, the loading level and loading zone have a slight influence on corrosion level, and the maximum difference of corrosion level caused by load is merely 0.23%. Furthermore, the corrosion level increases with the decrease of fractal dimension, suggesting that the non-uniformity of corrosion increases with the growth of corrosion level. The incorporation of slag powder can help reduce the non-uniformity of corrosion, but the influence on reduction of the corrosion level is about 0.25%. For concrete structures under marine environment, application of slag powder is a good method to slow down the corrosion and reduce the non-uniformity of corrosion.

“…On thorough examination, it involves specialists in the field of building structures and other related fields takes longer and is also cost much more expensive. Therefore, Federal Emergency Management Agency (FEMA) proposed a method called Rapid Visual Screening (RVS) to resolve the problem [8], [9], which is FEMA 154. The RVS is a procedure to evaluate the safety of buildings quickly and inexpensively subjected to earthquake loading.…”

Examination of vulnerability level of buildings to earthquakes is divided into two types, the quick checks (Rapid Visual Screening, RVS) and a thorough examination. On thorough examination, it involves specialists of the field of building structures and other related fields, takes longer and is also cost much more expensive. While a quick check, it does not involve many specialists in a particular area, does not require a long time and are relatively inexpensive. This study builds an assessment of the vulnerability of buildings quickly adapted from FEMA 154 to the conditions and rules that applied in Indonesia using a smartphone application. A Global Positioning System (GPS) technology is used to mark the location of the data of the examination. The smartphone application called RViSITS is used to simplify and speed up the examination process and sent via the internet, and the server as a gathering and processing data. Furthermore, from these data do building vulnerability mapping and disaster-affected areas, which can then be accessed by the public, government and private sectors as well as database information. In this research, the RViSITS application process is to apply the application to do a quick check on the buildings in Surabaya, so that later the database and mapping vulnerability condition of buildings owned by government institutions in Surabaya against earthquake loadings can be made. While in general, this application can be used any places, so that the database and mapping the vulnerability of buildings can be held any area in Indonesia.
