超长建筑结构温度应力分析

以郑州第二长途电信枢纽工程为例,对超长建筑结构进行整体有限元建模。针对7种不同类型温度荷载的特点,利用有限元分析程序ANSYS计算。给出了结构整体变形特点、结构中各种构件(梁、楼板、柱子及剪力墙)的温度内力变化范围以及分布规律。通过比较得出超长建筑在各种温度作用下的最不利工况。可为超长建筑结构考虑温度作用进行设计和施工提供参考。

Study on the Temperature Stress of Super- Length Building

Taking the Second Long Distance Telecommunication Hub Project of Zhengzhou for an example,this paper makes models of solid finite element to super-length building. According to characteristics of temperature load of 7 different types and using the ANSYS finite elements analysis program,it concludes the characteristics of the integral structural deformation,the scope and distribution of thermal inner force of different components,such as beam,floor slab,pillar and shear wall. After contrasting,it sums up the worse working condition for super-length building under different temperatures,which could provide references to the design and construction of super-length building by considering temperature actions.
