双塔连体结构风荷载作用下的反应分析
|
摘要
运用ANSYS有限元分析软件对不对称双塔连体结构和对称双塔连体结构进行了风荷载和竖向荷载作用下的内力分析。给出了两种连体结构在风荷载和竖向荷载作用下的位移、内力的分布规律;并对比分析了两种连体结构在风荷载和竖向荷载作用下结构的最大位移、最大等效应力的变化规律。为双塔连体结构的设计和应用积累经验。
The internal force of the unsymmetrical and symmetrical double-tower connected structures which are effected by wind and vertical loads is analyzed by using ANSYS finite element.On the influence of the two types of loads,distributing pattern of displacement and internal force is given out.And changing rule of the max displacement and internal force of the two structures are analyzed.On the basis of the above analysis,experience is accumulated for the design and exployment of double-tower connected structure.
