As a homeowner building a new home, you can include some safety measures to contruct a sound, earthquake proof home. The dissipation units are built into a building’s structural skeleton. Before doing this activity you should research how buildings in MEDC and LEDC countries can be designed and retrofitted to be resistant to earthquakes. Buildings designed under the current building code and those with base isolation fared well. Hidden inside the skeletons of high-rise towers, extra steel bracing, giant rubber pads and embedded hydraulic shock absorbers make modern Japanese buildings among the sturdiest in … Earthquake-resistance strength proved by East Japan disaster.
