【摘要】 自控耗能UPPC框架结构体系在罕遇地震作用下,依靠框架梁中设置的小型自控元件来实现释放框架梁中预应力筋的应力,使得框架梁梁端强度不超强,易于形成梁铰侧移机制。文章采用有限元软件对框架进行弹塑性静力分析(Pushover),对预应力筋的应力值及释放度进行研究,并对UPPC框架的出铰顺序进行分析,使得框架结构在罕遇地震作用下拥有良好的耗能机制。更多还原

【Abstract】 Under the rare earthquake action, UPPC frame structure system relies on the small automatic control components set in the frame beam to release the stress of the prestressed tendons in the frame beam, so that the beam end strength of the frame beam is not super strong, and it is easy to form the hinge side movement mechanism of the beam.In this paper, the elastoplastic static analysis(Pushover) of the frame is carried out by finite element software, the stress value and release degree of the prestressed tendons are studied, and the hinge release sequence of the UPPC frame is analyzed, so that the frame structure has a good energy dissipation mechanism under the action of rare earthquakes.更多还原
