@architectzvideos: Same load. Same concrete. Completely different outcome. 😳 The square column on the left is wrapped with rectangular ties (stirrups). The circular column on the right uses spiral reinforcement. As the load increases, the square column's corners spall off, the ties pop open, and the column collapses. The spiral keeps squeezing the core concrete from every direction, and the column stands strong. 💪 The secret? Confinement. The spiral resists the concrete's lateral expansion, giving the column more strength and far more ductile behavior. In earthquake zones, this detail saves lives. 🏗️ Which one would you trust? 👇 Comment below and tag your engineer friend!
