摩擦耗能框架水平荷载分配的计算方法研究

COMPUTATIONAL METHOD OF HORIZONTAL LOAD DISTRIBUTION FOR FRICTION 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,大都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。现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 which is one of the passive control techniques has been applied wildly in civil engineering. As yet, the finite element analysis method which requires complex calculation process for this structure system is not easy for civil engineer to handle and limits the further application of this system. So it is necessary to perfect the utility design method. The laws of the distribution of internal forces subjected to horizontal seismic action were discussed and a truss model of calculating was set up.
