Summary, etc. Current Finite Element Method (FEM) analysis approaches often underutilize the wealth of data generated and can be computationally expensive. While FEM provides rigorous structural analysis, practical interpretation relies heavily on sectional responses obtained through element meshing, neglecting the full picture of stress and strain distribution at the element level. Existing commercial FEM software also lacks comprehensive visualization capabilities.The 3D Applied Element Method (AEM) addresses these limitations by modeling structures using interconnected elements with springs. Stress and strain outputs are stored at the spring level, facilitating detailed interpretation of element-level structural response. Traditional damage assessment approaches often focus solely on the global structural level, hindering accurate prediction of localized damage behavior under load. This research presents a novel strain-based damage index (DI) implemented within the 3D AEM platform using FORTRAN 95. This DI, based on the second invariant of deviatoric strain, effectively captures damage propagation at the element level. The DI is normalized between 0 and 1 based on material properties, enabling a clear understanding of damage progression from an undamaged state to complete failure. The proposed DI was validated against experimental results and observed cracks in the Filiatrault Frame. The DI closely matched the observed crack propagation pattern, demonstrating its effectiveness. Furthermore, the DI was applied to a case study of an old school building in Dhaka, Bangladesh, highlighting its potential for retrofitting assessments of aging public structures. The building was subjected to ground motions scaled to the Dhaka spectrum with increasing peak ground acceleration (PGA) values (0.42g, 0.54g, and 0.61g). The strain-based DI successfully identified weak zones near the stairs, exceeding safe limits and progressively increasing with higher PGA values (0.016, 0.033, and 0.065 for the three cases). This proposed DI for reinforced concrete structures offers a valuable tool for seismic vulnerability assessment of existing infrastructure. By providing local damage insights, this method can significantly influence local authorities' policymaking regarding safety precautions during major earthquakes.
