“…Chen et al (Chen et al, 2014; Zhou et al, 2015) carried out a distributed indeterminacy evaluation considering the effect of member stiffness. And Jiang et al (2019) studied the influence of members’ material variation on the structural mechanical performance. At present, most studies can only analyze the mechanical properties of the whole structure in the current state (Gholipour et al, 2020; Gao et al, 2021; Kong et al, 2023), and then determine whether the structure is safe.…”

Corrosion will cause cross-sectional area loss of steel members, which will lead to redistribution of internal force and affect the performance of structures. In this paper, a generalized formula for the internal force variation of pin-jointed structures due to variation of external force, cross-sectional area, and initial length is derived. The area-loss sensitivity coefficient ( ASC) and the area-loss evenness coefficient ( AEC) based on statistical measures are then defined. By calculating these two coefficients, the influence of single member’s area-loss on the behavior of the structure as well as the evenness of internal force variation are evaluated. Besides, a method to determine the area-loss limit of pin-jointed structures is proposed based on the structural reliability theory and mathematical nonlinear programming. According to the above process, the effect of members’ area loss on structural properties is analyzed without complicated numerical approaches such as FEM, and then the safety of corroded structures is assessed preliminarily. The proposed method is verified by two numerical examples, and provides a convenient tool for pre-manufacturing, maintenance during service life, and structural health monitoring of pin-jointed structures.
