| 摘 要： | 在既有一榀框架受火实验的基础上,建立了该实验框架的精确有限元模型。通过与试验结果对比,获得了较好的温度场模拟结果。从结构抗火设计实际需要的角度出发,探究不同火灾发展因素对构件升温的影响,使用ABAQUS模拟多种参数化火灾模型下构件温度场分布。研究表明:有限元软件ABAQUS能够获得较精确的温度场分布;考虑多种随机性参数更有利于钢结构抗火工程。

| Abstract: | Based on the fire test of an existing frame, a finite element model of the testing frame was established. By comparison with the test results, better result of temperature-field simulation was obtained. In addition, considering the systemic design of the actual needs and exploring the effects of distinctive factors on the development of fire, the use of ABAQUS was to simulate the distribution of temperature-field under distinct fire models with varieties of parametric. The results show that: the finite-element software ABAQUS can obtain more precise temperature distribution; considering various random parameters is more conducive to the constructional steel fire engineering. |
