| 摘 要： | 建立了整体钢框架结构模型,采用有限元法对整体结构在火灾下的响应进行了数值模拟。对钢构件的应力和变形进行了弹塑性分析,得到了变形及应力随时间变化的云图和内力及挠度随时间变化的曲线。同时将不同约束条件下以及构件采取不同的保护措施时整体结构的响应进行了对比。为基于整体结构的耐火设计提供了有效的数值模拟方法。

| Abstract: | The model of integral steel framed structures is built.Finite element method is used to perform numerical simulation of integral structures under fire.Elasto-plastic analysis of thermal stress and deformation is carried out.As a result,the deformation,stress contours as well as the curves of inner force and deflection varying with time are obtained.The behavior of integral structures under different restrained conditions and protection measures are also compared.An approach to numerical simulation is developed for fire-resistant design based on integral structures. |
