| 摘 要： | 超长框架结构在温度场作用下的空间变形和内力特性是研究和解决温度裂缝的基础 ,以三维有限元模型为计算模型 ,运用通用有限元软件对结构在温度场作用下的空间变形特性和构件的内力进行了线弹性分析 ,总结了上述特性随层数、柱截面尺寸、板厚变化的规律 ,并对结构在恒载、活载、温度作用三种荷载工况下内力组合的结果进行比较 ,得出的结论对工程设计有一定的指导。

| Abstract: | The temperature deformation and stress of ultralong frame structures are the foundation of solving structures′ crack problem.Building a three dimensional FEM model with the general FEM software,the author does a parametric study with changing section dimension and thickness of column and board respectively.The internal force combinations of the structure under the action of dead load,live load and temperature effect are also compared, which has a practical significance for designing. |
