Description
Summary:Concrete However, it is necessary to note the main disadvantages of concrete filled steel tube columns. One of the most significant design deficiencies of traditional concrete filled steel tube columns is the practical absence of the hooped compression under operational loads due to lower values of the Poisson's ratio of concrete in comparison with steel, that is why the holder tends to break away from the concrete core in the elastic stage. It is offered to make concrete filled steel tube columns with a preliminary compressed concrete core to improve their design. The calculation procedure of the bearing capacity of concrete filled steel tube columns is given here in this article.
