Civil Engineering on Instagram: "Strong vs Weak Direction of Walls, Earthquake Resistance. Understanding the strong and weak directions of walls is crucial for designing earthquake-resistant buildings. Strong Direction of a Wall: When a force acts along the plane of the wall, it resists movement effectively. The wall remains stable as it utilizes its full length and height for strength. Weak Direction of a Wall: When a force acts perpendicular to the plane of the wall, the wall is vulnerable. Th
