It provides strong basement for the research of design . the method of structure analysis commended by this paper is based on nonlinear finite - element , diathermanous and elasticity mechanics . it found the model of a steel beam pressed by gravity and temperature in the condition of indoor fire 本文提出的结构分析法是在大量参数分析的基础上,以非线性有限元、传热学及弹性力学为基础,利用ansys软件,建立一个钢框架梁在室内局部火灾条件下的传热模型与在重力荷载及温度荷载共同作用下的受力模型。
The curve of deformation against loads is lent to study the symbols , and monitoring models , time - effect exponent , catatrophic models are used to distinguish the abnormal symbols . based upon the study of deformation procedure and its abnormal symbols , structrual analysis method is used to determine the deformation monitoring quota 此外,应用监控模型、时效分量、尖点突变模型等进行变形转异识别;在此基础上,采用结构分析法拟定特殊结构混凝土坝的变形监控指标。
