Concrete-filled steel tubular columns: Test database, design and calibration

Abstract

Concrete-filled steel tubular (CFST) columns are adopted in many structural applications, especially for tall buildings, bridges and large infrastructure due to their substantial structural and economic benefits. However, the design guidelines for CFST columns with high strength materials and slender sections are still limited. In acknowledging these limitations, a large number of tests on high strength CFST columns have been conducted. In this paper, the most recent experimental data on CFST columns with high strength materials and slender sections are collected and merged with existing databases to establish a comprehensive database with over 3100 tests. The test results are then compared ..
