Pinned or rigid? The type of connection defines how a structure behaves. In this video, we explore different column-to-ground and column-to-beam connections, showing how each one transfers forces differently. A fixed connection resists rotation by transferring moment, while a hinged connection allows it, completely changing the system’s response. This choice is fundamental in structural design, directly impacting stability, rigidity, and the distribution of internal forces. - Rotulada ou rígida?
