Research on Shear Buckling Performance of Curved Corrugated Steel Webs Under High Temperatures
In order to investigate the shear buckling performance of curved corrugated steel webs(CSWs)under high temperatures,a finite element model of the curved CSWs was established by the ANSYS software.Based on the con-sideration of the initial geometric defects of materials,the shear buckling performance of the curved CSWs were an-alyzed at various temperatures.Taking the thickness,height and curvature radius of CSWs as analysis parameters,the variation of shear buckling performance with temperature was studied under different influencing factors.The re-sults show that shear buckling performance of CSWs gradually decline with the increase of temperature;The more thickness of CSWs,the better the shear buckling performance,the more influence of temperature on the shear buckling performance;The height change has little effect on the shear buckling performance of curved CSWs.And the higher the temperature,the fewer the influence degree;The change of curvature radius has almost no impact on the shear buckling performance of curved CSWs,and the influence degree does not change with the temperature,which can be basically ignored.
