Generally, a precast concrete method (hereinafter referred to as 'PC method') is a method in which a structural member is manufactured in advance in a corresponding specialized concrete factory, is transported to a construction site, and assembled at a predetermined position It is a public law.

This PC method is used to solve the shortage of labor force at the construction site or reduce the cost by reducing the use of construction materials. For example, in the case of a structure having unit modules such as building structure and distribution center, It is possible to secure economical efficiency and construction workability by the construction, and it is possible to reduce the use of the formwork and the construction material by applying the dry method that installs the PC column manufactured at the factory and installs it in the field. And the method of construction, etc. have been actively carried out.

However, the conventional PC method is disadvantageous in that when a building collapses due to a natural disaster such as an earthquake or an external shock, it collapses in succession due to collapse of another layer or collapses another space in the same layer sequentially There is a problem that not only a great loss to the national industry and households but also a wound is caused due to a great expansion of human accidents and the like.
