The growing demand for energy-efficient buildings and diverse façade designs has increased thermal bridging at slab– balcony connections due to insulation discontinuity. Thermal break systems at these connections must ensure both thermal performance and structural stability. This study investigates a post-attached balcony thermal break system based on a precast concrete (PC) construction method through flexural and shear experiments, supported by finite element analysis using LS-DYNA. The results confirm stable structural behavior under both flexural and shear loading conditions and the numerical models successfully reproduce the observed damage mechanisms. The findings provide a basis for the structural evaluation and design of post-installed balcony thermal break systems.
