摘　　要：频发的火灾造成的巨大生命和经济损失提升了人们对建筑抗火性能的要求。但是结构抗火实验具有规模大、成本高、不可触及等特点,因此很难在高校开展相关的结构抗火试验。为了适应土木工程行业发展的需要,培养具有较强创新能力的后备人才,开发了建筑钢结构抗火模拟仿真实验平台,利用计算机技术开展结构抗火仿真实验。教学实践表明,该虚拟仿真实验平台能够摆脱时间和空间的限制,让学生们建立对钢结构建筑在火灾下破坏过程和破坏机理的直观印象,学习抗火实验的步骤、仪器和操作方法等知识,取得了良好的教学效果。The big loss of life and economy caused by fires attracts the attention on the fire resistance of buildings.However,there are many disadvantages on carrying out the structural fire resistance capacity experiment for the large scale of the test equipment,high cost of the test specimens and inaccessibility of the test progress,so it is difficult to conduct structural fire resistance tests in universities.In order to meet the needs of the development of civil engineering industry and to cultivate talents with strong innovation ability,a simulation experiment platform is developed to carry out steel structural fire resistance experiments by using computer technology.The teaching practice shows that the virtual simulation experiment platform can get rid of the limitation of time and space in carrying out the experiment.Students can establish an intuitive impression of the damage process and damage mechanism of steel structure buildings under fire,and learn the steps,instruments and operation methods of fire experiments,which has achieved good teaching effect.
