摘要
为了研究高温下钢梁的变形性能,使用ANSYS有限元程序建立了分析模型。计算分析了在小变形情况下梁的内力及变形;并且分析考察了由于梁挠度的增长而产生的悬链力对H型钢梁抗火承载力的影响。
It builds analysis model applying for ANSYS finite element program to research deformation performance of steel beam under high temperature, calculates ＆ analyzes inner force and deformation under small deformation, and analyzes influencing of catenary force to anti-fire load of H steel beam because of accretion of deflection.
