For the further study on stress concentration and fatigue property of tubular joints of concrete-filled steel, we designed the fatigue test on tubular joints of concrete-filled steel.Associating with the calculation of finite element, we studied the stress concentration, cracking source of fatigue, and fatigue -related rules including cracking expansion. I did the equivalent calculating under variable amplitude loading. We proposed the criterion of fatigue failure when surface length of penetrated crack is about 3 times as the thickness of the wall. According to the experiment we verified that the tubular joints under the amplitude load this criterion is reasonable, secure and feasible.

Glass is remarkable material and its functionality is significantly enhanced when it is processed or altered to provide added intrinsic capabilities. The overall performance of glass elements in a building can be further enhanced when they are designed to be part of a complete façade system. Finally, the façade system delivers greater performance to both the owner and the occupants of the building. A limited number of facade technologies or combinations of technologies can be evaluated in a field test program, for the reason of both resource constraint and the practical use. The specific method can be used to determine what technologies are to be selected for the research. It based on technical and market objectives, surveys of commercially-available technologies, manufacturers, architects and engineers, utilities, and other stakeholders.

In this paper, the microstructure and properties construction steel bars under various quenching and tempering temperature are investigated. Tensile tests show that the maximum tensile strength is1489MPa, elongation 11%, quenching temperature and tempering temperature have effects on the strength and plasticity of the samples, but the latter effect is more pronounced than the former. Steel bars have superior delayed fracture resistance between 390 ~420°C. The microstructure of steel bar is mainly composed of fine tempered sorbite (troostite) with carbide distributed along the lath martensite boundaries. Thus, we draw the conclusion thermal refining is an effective way to improve mechanical properties and delayed fracture resistance of high strength construction steel bars.

At present, the definition of smart cable is still not clear, however, the opinion that using the fiber optical sensing apparatuses as the sensing element of smart cable has formed a consensus in majority of study reports. In order to develop a new type of smart cable based on fiber Bragg grating (FBG), a scheme for fabricating smart cable which is compatible with production process of parallel steel wires cable is put forward. Aiming at the test range requirement, a novelty desensitized encapsulation structure is designed, which ensures the possibility to test steel wire strain of cable by FBG sensor. The single steel wire tension test in laboratory showed the design rationality of desensitized encapsulation structure which was reflected by the favorable linear relationship and repeatability of test results. After finish the on site tension test based on one fabricated smart cable, the proposed scheme feasibility that embedded novelty desensitized encapsulation FBG strain sensor in cable to form a new type of smart cable was verified. Test results showed that the survival rate of sensors in smart cable was high. Meanwhile, there was a clear linear relationship between the output test signal of smart cable and the tension loads and the test repeatability was acceptable as well. Finally, several improvement suggestions relating to the successful application of the proposed scheme about smart cable in actual engineering were also indicated.

Published: October 2011

By using finite element software ABAQUS, the nonlinear finite element analysis of earthquake resistance behavior of L-shaped concrete-filled rectangular composite steel tubular columns is carried out, furthermore, the analysis results and the corresponding experimental results are compared. The results indicate that the finite element calculated value of ultimate bearing capacity is less than experimental value; axial compression ratio of the specimen has little affect on its ultimate bearing capacity and earthquake resistance behaviors; the results of FEM analysis can match the experiment results better, and thus, it can better reflect the earthquake resistance behaviors of the specimens.
