In this paper, the hysteresis tests of six circular steel reinforced concrete-filled stainless steel tubular (SRCFSST) columns and three circular concrete-filled stainless steel tubular (CFSST) columns were carried out to study the hysteresis behaviors of SRCFSST columns. The main parameter investigated in the tests was the axial load ratio. The tests reveal that the typical damage mode of circular SRCFSST columns is compression-bending damage, including profiled steel buckling, steel tube buckling, and concrete crushing. When the axial load ratio is relatively low, the stainless steel tube

To study the mechanical properties of high-strength structural steel in fire, this paper investigated the mechanical properties of domestic Q550D high-strength structural steel during the fire heating and cooling stages, including the elastic modulus, yield strength, ultimate strength, ultimate strain, and elongation at break, by using the steady state test method. A cooling stage influence coefficient was adopted to reflect differences in the mechanical properties of steel between the cooling and heating stages. The results indicate that the mechanical properties of Q550D steel at the cool

To investigate the fire resistance performance of multi-ribbed composite walls, two full-scale multi-ribbed composite walls were subjected to single-and double-sided fire tests, respectively. The temperature fields, displacements, fire resistances and failure modes of the walls were obtained. It is observed from the test that, under single-sided fire, a significant temperature gradient formed inside the wall along the thickness direction. When damaged, the temperatures of the autoclaved aerated concrete blocks and the concrete of the ribbed beams and ribbed columns on the surface unexposed

In this paper, nine axially loaded bolted glued laminated bamboo connection specimens were designed and tested at normal temperature and in fire to investigate the fire endurance of spliced connections subjected to axial loading. The test parameters included connection type, bolt end distance and load ratio. The fire endurance was determined based on the test results. The results indicate that the bolt end distance has an important influence on the failure modes of the specimens tested at normal temperature. Splitting failure perpendicular to the bamboo grain direction and longitudinal shea

In order to study the evolution of mechanical properties of corroded steel at high temperature, high temperature tensile tests were conducted on 12 mm thick Q355 weathering steel that had been in service for 10 years. The damage morphology, stress-strain curve and mechanical property degradation law of corroded steel at different temperatures were discussed. A numerical analysis model considering the surface morphology of corroded steel was established using three-dimensional reverse reconstruction technology. The development law of surface stress of corroded steel at different temperatures
