“…The SQAF previously proposed by the authors [4] (see Figure 1) has six components: (1) input data; (2) quantification of reinforcement corrosion and its effects on the damage zone and materials' properties; (3) evaluation-ULS: evaluation of columns' performance under combined corrosion and ultimate loads; (4) evaluation-SLS: evaluation of columns' performance under combined corrosion and traffic loads; ( 5) evaluation E-ULS-EQ evaluation of columns' performance under corrosion and ultimate seismic loads as part of evaluation-ULS only in high-risk seismic zones [4]; and (6) semi-quantitative assessment and reporting. Nonlinear Sectional Analysis (NLSA) is the basis for evaluating the columns' performance under corrosion and ultimate seismic loads as part of evaluation-ULS only in high-risk seismic zones [4]. The evaluation of the column structural performance under combined reinforcement corrosion and ultimate loads and the evaluation of the column structural performance under combined reinforcement corrosion and traffic loads are presented in Mohammed et al [21], [22].…”

“…The SQAF proposed by Mohammed et al [4] identifies four major damage cases due to reinforcement corrosion: (a) flexural cracking of concrete due to corrosion; (b) spalling of the concrete cover; (c) rupture of one or more stirrups; and (d) in a more advanced state of corrosion damage, structural failure of the column through complete loss of confinement and/or rebar(s) buckling. It is essential to mention here that the focus is on the last three damage cases, where damage case (a) can be considered as part of damage case (b), in which the impact on the structural behavior is more apparent.…”

“…Such an approach would quantitatively evaluate bridges' structural performance when safety-critical elements (bridge columns, for instance) are partially damaged. Mohammed et al [4] proposed a semi-quantitative assessment approach, introducing a Limit States Evaluation method (LSE). The LSE is analogous to the Limit States Design (LSD) method in North American bridge design codes [5]- [6].…”

“…This paper aims to present a Simplified Nonlinear finite element Seismic Analysis (SNLSA) of corrosion-affected RC columns developed as a tool for the evaluation of the seismic response. The SNLSA is part of a Semi-Quantitative Assessment Framework (SQAF) proposed by Mohammed et al [4] to evaluate the serviceability and ultimate limit states of RC bridge piers affected by reinforcement corrosion. The analysis approach involves an enhanced inspection and material testing as a major input source to evaluate the column's instantaneous structural performance.…”

Severe reinforcement corrosion significantly reduces the structural stiffness and load-carrying capacity of Reinforced Concrete (RC) columns. The interactive effects of corrosion-induced damage and repeated traffic load cycles further accelerate bridge columns' load-carrying capacity deterioration. When subjected to seismic excitation, corrosion-affected RC columns could show a dynamic response significantly different from non-affected columns. This paper proposes a Simplified Nonlinear finite element Seismic Analysis approach (SNLSA) based on enhanced inspection of corrosion-damaged RC columns and as a handy tool for evaluating their seismic response, which is a crucial step in a semi-quantitative assessment framework. The SNLSA integrates Nonlinear Sectional Analysis (NLSA), DRAIN-RC computer program for nonlinear time history analysis, and Takeda's hysteretic analysis. The approach provides three options: (i) establish the staged failure mechanism using express analysis simulating quasi-static loading up to failure; (ii) use a more comprehensive analysis simulating cyclic loading developing the hysteretic relationships; and (iii) conduct a nonlinear full time-history analysis. The SNLSA can estimate the significant contraction of the column interaction capacity when subjected to severe corrosion damage for all load-over-capacity ratios. The SNLSA quantitatively predicts the change in the seismic performance of corrosion-affected versus as-built bridge columns. The approach could also be used to select the appropriate design option for bridge columns in seismic-critical zones.

Given the advances in technology and the development of urban development and progress in people's lifestyles, the use of bridges is considered as an important and necessary way of esophageal communication. Bridges are one of the most important tools for connecting roads and different cities, which connect different areas and create connections between people. One of the most important and necessary measures in the bridge industry is related to the repair and maintenance of bridges, which cost less than building a bridge and help to create connections between people. To this end, the present study examines the effects affecting the maintenance and repair of bridges in urban contexts and for this issue an approach under conditions of intuitive fuzzy uncertainty based on analytic network process and comprise solution methods to calculate weights and option ranking offers. Finally, in order to validate the proposed method, a case study is used along with a comparison of the proposed method and existing methods in the literature. The final results indicate the strength and efficiency of the proposed method in calculating weights and ranking options for the project of maintenance and repair of urban bridges in Rasht.

Corrosion of reinforcing steel in reinforced concrete (RC) infrastructure is one of the most concerning durability problems affecting its serviceability and ultimate capacity in North America. The rise of greenhouse emissions in recent decades and the use of de‐icing salts during the winter increase the potential risk of corrosion. Furthermore, global warming could lead to higher freeze–thaw cycles (FTC) frequency in cold regions. The combined effects of corrosion and frost damage tend to affect aging RC infrastructure's structural performance and service life. The present study adopts comprehensive reinforcement corrosion and frost damage models from the literature and proposes a stage‐based damage analysis scenario. Three‐dimensional nonlinear finite element analyses using the commercially available finite element program DIANA are conducted to evaluate the structural performance of RC bridge piers under the synergetic effects of FTCs, corrosion, and service load during their service life. The proposed methodology for each damage mechanism is assessed by comparison with available experimental data from the literature. The synergetic effects cannot be validated because there is no data, but the methodology highlights the deterioration rate at which several mechanisms acting at the same time can affect the structural performance of these members.
