Concrete-filed steel tube columns in construction high-rise building and structures

Building constructions, buildings and structures

Modern construction is characterized by an increase in height of buildings and spans of overlaps, etc. This requires the use of columns having a high load bearing capacity at small cross-sections. One of solutions to this problem is to use concrete-filled steel structures. The article provides an overview of the application of these structures in foreign countries. The basic advantages and disadvantages of concrete-filled steel structures are stated. The basic problems of their application in modern construction and ways of theirsolution are given.
