Damage Measures for Performance-Based Design of Rectangular Concrete-Filled Steel Tube Members and Connections
Damage evolution of rectangular concrete-filled steel tube (RCFT) column and beam-column members as documented in experimental tests is presented in this paper. An experimental database was first constructed that included RCFT tests available in the worldwide literature. Based on the experimental data, appropriate damage states for RCFT members, connections, and frames were defined at different...
متن کاملSeismic Demand and Capacity Evaluation of Rectangular Concrete- Filled Steel Tube (RCFT) Members and Frames
This paper presents analysis tools to be used in quantifying the demand and capacity of composite frames composed of rectangular concrete-filled steel tube (RCFT) columns and steel girders. Worldwide experimental research on RCFT members were consolidated into a database. The experimental results stored in the database were used to quantify the capacity of RCFT members at multiple levels of loa...
متن کاملDamage Assessment for Performance-Based Design of Rectangular Concrete-Filled Steel Tubes
This paper summarizes research in which the damage evolution of rectangular concrete-filled steel tube (RCFT) members, connections, and frames, was documented using results from experimental tests from around the world. Two types of damage indices were then defined and used for each type of RCFT component to quantify damage. Based on the quantified values of damage, each local damage level iden...
متن کاملBehavior of FRP-Confined Concrete-Filled Steel Tube Columns
This paper presents the results of an experimental study into the behavior of concrete-filled steel tube columns confined by fiber-reinforced polymer (FRP). Eleven columns were tested to investigate the effects of the FRP layer number, the thickness of the steel tube and concrete strength on their load capacity and axial deformation capacity. The experimental results indicated that the FRP wrap...
متن کاملCyclic Evolution of Damage and Beam-column Interaction Strength of Concrete-filled Steel Tube Beam-columns
The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...
