"This 3D visualization provides a transparent look into the skeleton of a reinforced concrete structure, focusing on the critical beam-column joints. The model highlights the intricate arrangement of the reinforcement cage—showing how longitudinal bars and transverse stirrups interlace to resist axial loads, bending moments, and shear forces. ​The continuity of the steel bars through the joint ensures a robust load transfer mechanism, which is vital for the stability of high-rise buildings.
