Fire at building can occur enormous damages to life, properties, and environment and the risk of fire breakout is going up higher because of application of combustible materials than before. Therefore, the steel industries are trying to develop fire resistant steel in order to sustain the load bearing capacity of steel structures during fire situation. In this paper, to give the basis data-bases for evaluation of structural stability of steel structures applied fire resistant steel, FR 490, the tests of mechanical and thermal properties at high temperature were conducted and the comparisons are done with the SM 490 that has the same mechanical one. Keywords :Fire resistant steel, 0.2% offset proof stress, Mechanical property at high temperature, Thermal property at high temperature 1. 서 론 1

Abstract. High Strength Concrete Filled Steel tubes (CFST) provide a common construction material in China. The purpose of this research was to determine the axial load properties for CFST subjected to concentric and eccentric loading in a series of experiments. The results show that the magnitude of experimentally measured compressive strength increases for the core concrete, due to the confinement from the steel that is proportional to the ratio of the area of steel to the area of concrete. If the slenderness ratio is kept constant the columns bearing capacity and maximum strain decreases as the eccentricity to radius ratio increases. Formulas to estimate the load bearing capacity for short and for slender eccentrically loaded columns were established from the data. The results have been compared statistically to other published results to show that a general linear form of the capacity equation is warranted for High Strength Concrete Filled Steel tubes. Keywords:Concrete filled steel tubes, high strength concrete, bridge construction. IntroductionThe purpose of this research is to experimentally investigate the properties of concrete filled steel tubes (CFST) using a high strength concrete core. The experimental work investigates the ductility and strength properties of steel tubular columns filled with a high strength concrete core, using short and slender columns subjected to either concentric or eccentric loads. The results are compared to recent published data from the USA, Australia, and China [1][2][3][4][5][6][7][8][9][10][11][12]. The protocol for the column compression tests used both concentric and eccentric load rigs. The columns used in the experiments have length to diameter ratios ranging from 3.5 to 15. This paper outlines the literature relevant to this work, provides a methods section, outlines and summarizes the results and the key findings, and provides a conclusion. Literature ReviewCFST column types have been used in recent high-rise structures in China [13][14][15][16][17][18][19][20][21][22]. CFST structures are emerging as an important structural system for new buildings, particularly for providing earthquake resistance. Steel tubular columns filled with normal strength concrete (NSC) have been studied using slender and eccentrically loaded units [23,24], and based on these studies; a design code has been established for Chinese use [25]. A sketch of a typical CFST building connection showing a column and beam connection is drawn in Figure 1. This sketch provides the definitions of the steel wall thickness, diameter of the steel tube and the area of the concrete core of the composite tube. The schematic format of the connection detail shown in Figure 1 comes from a recent Chinese building. The connection detail has been simplified by reducing the number of bolt holes and stiffener plates. The steel plate for the beam connection transfers the load to the steel tube, which relies on the concrete to provide buckling restraint and increased strength for the given cross-sectional area.An ea...
