Inside History on Instagram: "Japan’s earthquake-resistant infrastructure is among the most sophisticated globally, built to safeguard lives and property in one of the planet’s most seismically active zones. The country enforces rigorous building codes that mandate the use of reinforced concrete, flexible steel frameworks, and base isolation systems that enable buildings to sway safely during quakes. Many high-rise structures are outfitted with tuned mass dampers or water tanks to absorb and red

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
