As modular structures grow taller, the impact of lateral loads becomes more significant, making the stiffness of module connections a critical factor. In practice, these connections are often analyzed as rigid, but their actual stiffness tends to align more closely with simple or semi-rigid connections. This highlights the need to accurately evaluate connection stiffness and reassess practical design approaches. This study analyzed the stiffness of 68 specimens from existing modular construction experiments, applying the connection stiffness classification criteria from AISC360-22 and EC3. Additionally, pushover analysis was conducted to compare the structural behavior of systems with rigid, semi-rigid, and simple connections. The results showed that the actual stiffness of modular connections was approximately 10% lower than rigid connections, with a similar 10% reduction in performance during pushover analysis. Structures with rigid connections exhibited the highest load-sharing ratio for shear walls. These findings suggest that when designing rigid modular connections, it is essential to reassess the safety of shear walls and adopt a more conservative design approach to account for potential stiffness deviations.
