Test on Hysteretic Behaviour of Prestressed Composite Joints with Concrete-Encased CFST Columns

Hysteretic Behavior of Prestressed Concrete Bridge Pier with Fiber Model

The hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier were researched. The effects of the prestressed tendon ratio, the longitudinal reinforcement ratio, and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method. The analysis show...

Flexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections

The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...

Study on Axial Compressive Behaviors and Bearing Capacity Formulas of the Composite CFST Columns

research behavior of concrete filled steel tube columns, cfst

concrete filled steel tube columns (cfst) are a kind of composite columns according to advantages of cfst relative to reinforced concrete and steel columns. use of these materials is common in recent years especially in high building, unnecessary of molding, high ductility, proportionate resistance with low volume, economical, low deformation relative to steel columns are among advantages. in t...

Nonlinear finite element analysis of Concrete Filled Steel Tube (CFST) columns under projectile impact loading

This paper presents a three dimensional nonlinear finite element analysis for Concrete Filled Steel Tube (CFST) columns subjected to lateral impact load. The finite element models were developed using commercial code ABAQUS/Explicit, which were validated against the experimental results. The study has been carried out to examine the influence of several parameters such as the length of the tube...
