英文摘要	This study presents an innovative numerical model based on the position-based finite element method, utilizing laminated frame elements to predict beam displacements under corrosion-a common challenge in reinforced concrete structures due to chlorides and carbon dioxide penetration. The proposed model addresses both geometric and physical non-linearity, specifically considering the uniform reduction in rebar area, a critical consequence of carbonation-induced corrosion. This reduction significantly influences element inertia and, consequently, the structure's stiffness. Given the expected increase in corrosion problems in reinforced concrete structures due to climate change-induced rising temperatures and heightened carbon dioxide levels, resulting in earlier degradation and reduced stiffness, there is a pressing need for alternative approaches to calculate structure displacement under carbonation-induced corrosion. In response to this concern, our model provides an innovative and alternative methodology, demonstrating promising results when compared with existing literature, even under the constraints of a simplified model.
