摘要
根据多跨超长预应力混凝土框架结构在竖向荷载及水平地震作用下的受力特点,提出了结构应选择混合耗能机制,并论证了由重力荷载控制配筋设计的多跨超长预应力混凝土框架结构中采用混合耗能机制的必要性和合理性。
According to the character of prestressed concrete frame structures (PCFS) under the vertical and lateral load, it is necessary to select the mixed energy dissipation mechanism to design PCFS. The pushover analyses (SAP2000) are used to prove the necessity of the realization of the mixed energy dissipation mechanism in the PCFS with large longitudinal length.
