Experiments and simulations assess moment resistance in bolted connections, indicating key structural parameters.

The research aims to analyze the behavior of end-plate bolted connections with varying configurations under loading conditions.
Conducted experiments on two full-scale joint specimens: one with two bolts and another with four bolts per row.
Developed Finite Element models using ABAQUS to simulate and analyze connection behavior under monotonic loading.
Performed a parametric study to evaluate the influence of parameters such as end-plate thickness and bolt diameter.
The connection with four bolts exhibited higher moment resistance and greater initial rotational stiffness than the two-bolt configuration.
Force-displacement and moment-rotation curves showed strong agreement between experimental and numerical results.
Recommendations were made for moderating end-plate thickness in relation to bolt diameter and the necessity for web stiffeners.

Gjukaj et al. (2025) studied this question.
