碩士 === 國立成功大學 === 土木工程學系碩博士班 === 96 === This thesis presents the results of investigating the structural behavior of steel beam-column moment connections in fire. The finite element software ABAQUS has been used to analyze the three full-scale tests of H-beam to box-column moment connections carried out in ABRI. Two kinds of materials, SN490B and SN490C-FR, have been considered. The material properties of steel at high temperature are adopted from material test and relevant documents in this study. The comparison between the measured results of the beam end displacement and the joint rotation and numerical results shows that they agree well with each other. The proposed model is verified to capable of predicting the steel structural behaviors in fire. The structural behaviors with different exposure surfaces which can be used to assess the structural safety in fire also have been analyzed.
