Preliminary Research on Mechanical Behavior of Steel Frame Filled with Steel Plate Shear Wall after Exposure to Overall Stage of Fire

Abstract:

For a further study on the fire-resistant performance of steel plate shear wall under overall stage of fire, a numerical analysis model of steel frame filled with steel plate shear wall was built with the finite element software ANSYS. The stress and displacement distribution at different moments were calculated through the thermal structural coupling analysis acording to ISO-834 standard fire curve, by reasonable selection of the thermal parameters, which showed the highest temperature appeared on the heated side of the beam in the process of heating up, while the highest temperature in the stages of cooling and natural cooling appeared in the column-beam connection; The temperature of structure was elevated for 11minutes, then dropped for 64.5minutes and finally the structure was cooled in the air for 60.5minutes. The whole process shows that the lateral load-bearing capacity of the steel frame filled with steel plate shear wall was reduced by about 30 percent, compared to room temperature.
