Durability and Concrete Strain Capacity of Concrete Filled Steel Tube Columns with Hooped Reinforcement

摘要

Definition matters of strength and strain capacity properties of the concrete filled steel tube columns with hooped reinforcement are considered. Theoretical approach to consideration of power resistance of concrete filled steel tube columns with hooped reinforcement in the form of grids allowed receiving new dependences for determination of durability and limiting deformation of volume compressed concrete. Practical use of these dependences will allow increasing the bearing ability calculations accuracy for the concrete filled steel tube columns with hooped reinforcement.
