Over the past decades, many prefabricated concrete structures have been built in earthquake zones around the world. In more advanced earthquake countries, such as the United States and New Zealand, the prehistory system dates back to the 80's (more than three decades ago). In addition to the use of prefabricated frames with joint joints, the use of prefabricated concrete members in flexural frames has also attracted the attention of engineers in such a way that today, structures with flexural frames containing columns, columns, walls and ceilings Prefabricated buildings and experience of relatively large earthquakes are also seen in these countries. The variety of building technologies is enormous, and each of its features has its own limitations. The system of prefabricated lightweight structures was developed some 34 years ago by an American. The industrialization period lasted 5 to 6 years. The major companies that use this technology in the world are Austrian E.V.G and 3D Panel and RAM companies in the United States. The European industry's great attention to the technology of lightweight prefabricated structures was due to problems that were encountered in other pre-fabricated technologies.
