摩擦耗能框架剪力分配的计算方法研究

COMPUTATION METHOD OF SHEAR FORCE DISTRIBUTION FOR ENERGY DISSIPATION BRACED-FRAME SYSTEM

近年来,耗能支撑框架体系作为一种有效的被动控制技术在工程界得到了广泛的运用。但是现阶段对该体系的计算方法还很不成熟,大多采用有限元方法进行空间整体分析,不便于设计单位使用,从而限制了这种结构体系的进一步推广应用。本文拟就摩擦耗能支撑框架在水平荷载作用下的内力分配规律进行研究,提出实用的设计方法。

The energy dissipation braced - frame system as a passive control techniques has been applied widely in civil engineering. But the finite element analysis method which requires complex calculation process for this structure system is not easy for civil engineer to handle and limites the further application of this system.So it is necessary to perfect the utility design method. In this paper, the laws of the distribution of horizontal loads action were discussed and a truas calculation model was set up.
