“…However, in reality, columns acting as part of a frame exhibit different behavior from that of isolated ones in fire, because of the considerable restraint and continuity provided by abutting structure. In the past decade, research has been concentrated * Correspondence should be addressed to: Yi-Hai Li, E-mail: yihai.li@mail.scut.edu.cn on the behavior of restrained steel and composite columns in fire [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. However, the same level of development has not taken place for RC columns.…”

This paper describes the performance of 12 axially restrained RC columns (four for each type of cross section, i.e., +-, T-and L-shaped cross section) under fire conditions that were recently finished in South China University of Technology. The main objective of the paper is to investigate the effect of axial restraint on RC columns during both expanding and contracting phases. The RC columns were all initially concentrically loaded and subjected to ISO834 standard fire on all sides. Axial restraints were imposed at the top of the columns to simulate the restraining effect of the rest of the whole frame. Different degrees of axial restraint were obtained by varying the length of the restraining beam. The boundary conditions of the columns were considered as fixed-fixed for all tests. It is found that restrained RC columns behave quite differently to isolated ones. No typical 'runaway' failure of isolated RC columns was observed in the fire test. Finally, the finite element software, SAFIR, is employed to conduct a numerical analysis of the tests.

“…These design guidance were developed to determine the failure temperature of a stainless steel structural member subject to a constant load. The performance of cold-formed steel structural members at elevated temperatures has been investigated by Ranby [8], Feng et al [9], Dharma and Tan [11], Tan et al [10], Lim and Young [12] and Chen and Young [13], but the works have been focused on carbon steel rather than stainless steel structural members. In order to improve our understanding on fire resistance of stainless steel members, the performance of stainless steel members at elevated temperatures is investigated in this study.…”

“…Valente and Neves [28], Rodrigues et al [29] and Tan et al [30] studied the fire resistance of mild steel columns and found that the presence of axial restraint would decrease the critical temperature, which is the temperature at which failure of the member occurs. Wang and Ge [31] conducted a similar research on four Q460 H-shaped columns using two levels of axial constrained stiffness and two levels of axial load ratio.…”

Fire-resistant and high temperature behavior of high strength steels (HSS) for structural engineering applications has become an important research topic in recent years. In this paper, a succinct review of HSS behavior under and after high temperature exposure is provided. The review addresses the following aspects of HSS: (1) their mechanical properties under and after fire exposure, (2) residual stress in welded HSS sections, and (3) high temperature performance of HSS columns. Recent studies have demonstrated that different grades of HSS can exhibit noticeable differences in their mechanical properties under and after fire exposure, and different cooling methods could have an effect on the post-fire mechanical properties of HSS. Because current design standards for steel structures under elevated temperature were developed based on mild steel, care must be exercised when applying these standards to HSS as they are not necessarily applicable.
