In this paper, in order to grasp the characteristics of the RC buildings under consideration of the construction of remaining some prop by received three-layer collected the structure diagram and design strength, structure calculation root and each we extracted and analyzed the structural elements. As a result, among RC buildings under consideration of the construction of remaining some prop by received three-layer it was found that most of the buildings of the RC floor slab without the small beams are buildings of 3 to 15 stories in multi-family houses.
