Seismic 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 کاملDevelopment of Seismic Demand and Capacity Assessment Methodology for Rectangular Concrete-filled Steel Tube (rcft) Members and Frames
Accurate assessment of demand and capacity of structures is critical in developing performance-based design methodologies. In this research, new methods are presented towards quantifying demand and capacity of RCFT frames and members. An experimental database was compiled documenting local damage levels of RCFT members. The quantified information collected from the experiments was utilized in c...
متن کاملSeismic Design of Concrete-Filled Circular Steel Bridge Piers
The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...
متن کاملAdvanced Analysis and Seismic Design of Concrete-Filled Steel Tube Structures
This paper will focus on aspects of the advanced analysis and underlying behavior of composite structures with concrete-filled steel tube (CFT) columns. Through a detailed examination of the results of a suite of full-scale slender CFT beam-column tests, insight into the cyclic behavior of such members is gained, specifically pertaining to local buckling of the steel tube and the plastic hinge ...
متن کاملA Synopsis of Studies of the Monotonic and Cyclic Behavior of Concrete-Filled Steel Tube Members, Connections, and Frames
A significant amount of research has been conducted worldwide on the behavior of concrete filled steel tubes (CFTs) in the past five decades. This report provides a summary of the behavior and experimental work of concrete filled steel tube members, connections, and frames that are reported in detail in the literature. These published studies have been summarized with an emphasis on experimenta...
