Based on axially compressive tests on 6 short columns and 27 slender columns of lightweight aggregate concrete filled steel tube (LACFST)，macroscopic deformation characters，axial force-longitudinal strain curves，failure mode and failure mechanism are studied. The results are also compared with these of the normal concrete filled steel tube. The test results demonstrated that slenderness ratio is the main influence factor to the behavior of LACFST long columns under axial load. The greater the slenderness ratio is, the lower the ultimate bearing capacity and stability coefficient of the specimen are, and the performances of core concrete affect the stability behavior of lightweight aggregate concrete and normal concrete filled steel tube long columns. The stability coefficient of specimens is determined by the peak strain of concrete and unrelated to the peak strength of concrete. The stability coefficient increases when the peak strain of concrete increasing. Comparison results show that calculation formula in Europe code EC4 (1996) can be applied to calculate the bearing capacity of LACFST columns under axially compressive load.

“…Similar to RC and CFST arch bridges 8), 9) , the scaffolding method, cantilever method and swing method are used for steel arch bridge construction. In addition, the lightweight quality and high stiffness of steel arch bridges enable the use of launching and large block methods for the whole superstructure or large segments of the structure.…”

A review of the current status and progress of steel arch bridges in China and Japan, as well as an outline of the design vehicle load and design method against global buckling for such bridges, is presented in this paper. The existing steel arch bridges in China and Japan were analyzed in terms of year of completion, main span length, structure type, main arch rib form and construction method. It is shown that the steel arch bridge in China has developed rapidly since 2000, characterized by a long main span, while in Japan it has stepped into a fast-growing period since 1955, with medium and small bridges holding a great majority. As for the main span length, most of the bridges have a span from 100m to 250m in China, while majority of bridges are shorter than 150m in Japan. Over 80% of the bridges in China are through and half-through bridge types, and the arch ribs are hingeless structures. However, over 88% of bridges in Japan are deck and through bridge types, and a two-hinged structure was mostly adopted in through and half-through bridges. Single-hinged and three-hinged arches were seldom adopted in the two countries. The rise-to-span ratios of the arches in China and Japan are mainly in the range of 1:6-1:4 and 1:7-1:5, respectively. Most of the arches both in China and Japan use solid box ribs, and only a small fraction uses truss ribs, in which box sections are mostly adopted for the truss members. The cantilever method and scaffolding method are the two main construction methods used in China and Japan, although some other construction methods have also been developed.

“…Concrete-filled steel tubular (CFST) structures have been studied and used in civil engineering widely for many years [7]. However, steel tubes are susceptible to degradation due to corrosion and its thin-walled section before concrete hardening [8], which results in the decrease of axial strength of the CFST column [9]. erefore, the CFRP-metal tube can also be used in civil engineering, for example, the CFRP-steel composite tube infilled with concrete has been used as the column [10], and CFRP has also been used to reinforce damaged CFST column [11].…”

is paper presented a comparative study of concrete-filled steel tubular (CFST) stub columns with three different confinement types from carbon fiber reinforced polymer (CFRP): outer circular CFRP, inner circular CFRP, and outer square CFRP. e compressive mechanism and physical properties of the composite column were analyzed firstly aiming at investigating the confinement effect of CFRP. Ultimate axial bearing capacity of these three CFRP-confined CFST columns was calculated based on Unified eory of CFSTand elastoplastic limit equilibrium theory, respectively. Meanwhile, the corresponding tests are adopted to validate the feasibility of the two calculation models. rough data analysis, the study confirmed the ultimate strength calculation results of the limit equilibrium method were found to be more reliable and approximate to the test results than those of Unified eory of CFST. en axial bearing capacity of the pure CFSTcolumn was predicted to evaluate the bearing capacity enhancement ratio of the three types of composite columns. It was demonstrated that the averaged enhancement ratio is 16.4 percent, showing that CFRP-confined CFST columns had a broad engineering applicability. rough a comparative analysis, this study also confirmed that outer circular CFRP had the best confinement effect and outer square CFRP did better than inner circular CFRP. e confinement effect of CFRP increased with the decrease of concrete strength, and it was proportional with relative proportions of CFRP and steel under the same concrete strength.
