Ambient and fire behavior of eccentrically loaded elliptical slender concrete-filled tubular columns
This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behavior of such innovative cross-sections under ambient and high temperatures. The test parameters covered in this experimental program were the load eccentricity (0, 20 and 50 mm) and the type of infill (plain concrete or bar-reinforced concrete). Six room temperature tests were performed, while other six tests were carried out at elevated temperatures, under both concentric and eccentric axial loads. Using the results of these tests, the current provisions of Eurocode 4 for room temperature and fire design were assessed, and a specific design proposal developed by the authors was evaluated. ; The authors would like to express their sincere gratitude to the European Union for the help provided through the Project RFSR-CT-2012-00025, carried out with a financial grant of the Research Programme of the Research Fund for Coal and Steel (RFSR-CT-2012-00025). ; Espinós Capilla, A.; Romero, ML.; Portolés Flag, JM.; Hospitaler Pérez, A.
