Material Properties Of Steel At High Temperatures And Its Application To Structural Analysis Of Steel Frame Under Fire Condition

Material properties of steel change under fire condition, which is a main reason why cause fire response of steel structures at high temperatures. So the research on fire resistant structural analysis of steel frame should pay close attention to the model of material properties of steel. And one of the most important problems for fire resistant structural analysis is to build and apply the mechanical models of steel materials at elevated temperature, which is also decisive for the results of structural analysis.The paper makes a conclusion of the research on the material properties of steel and pays close attention to the rules of the change of the material properties under fire condition, which make a basis for the reasonable analysis of steel structures at high temperatures.The paper carries out the analysis of fire response of steel frame at high...
