In load bearing walls structure, the building is constructed with continuous vertical walls to support the floor slabs at different levels. This resource page provides an introduction to the concepts and principles of seismic design, including strategies for designing earthquake-resistant buildings to ensure the health, safety, and security of building occupants and assets.The essence of successful seismic design is three-fold. Examples of such applications are the Cathedral of Our Lady of the Angels and the Acropolis Museum. On May 9, 2009, one unit (Unit 7) was restarted, after the seismic upgrades. [2] According to the Earthquake Engineering Research Institute, precast panel buildings had good durability during the earthquake in Armenia, compared to precast frame-panels. The ideal combination is use of reinforced steel with concrete. Earthquake contractor should be registered in the state/province/country of the project location (depending on local regulations), bonded and insured [citation needed]. Earthquake Resistant Design Philosophy Building should resist minor earthquakes (
