中文摘要：

通过ANSYS软件建立高层框架结构的三维有限元模型，模态分析结果显示结构的第三阶模态为扭转振动，在地震作用下高层框架厂房结构的扭转振动将占据主要位置，需要对结构的扭转反应进行控制。提出将厂房附属设备气化炉作为控制装置中的子结构质量块，设计合理的多重调谐质量阻尼器（MTMD）参数。对结构在施加MTMD和未施加MTMD两种情况下进行动力时程分析，研究MTMD对高层框架厂房结构在两种地震作用下抗扭转性能的影响。结果表明，在地震作用下，MTMD对高层框架结构角位移和角加速度的控制效果较好。

英文摘要：

A finite element model of the structure is established with ANSYS, and modal analysis results show that the third modal of the structure is torsional vibration. Torsional vibration frequency is low that it is easily aroused, and torsional vibration of high-rise reinforced concrete frame mill construction under earthquake actions will occupy the main position, so the torsional response of the structure needs to be controlled. It was put forward that the gasifier of the plant is taken as the additional mass of the control device, and the reasonable parameters of MTMD were designed~ By carrying out dynamic time history analysis of the structural with and without MTMD, it was investigated the influence of the MTMD against torsion properties of high-rise reinforced concrete frame under earthquake actions. The results show that the MTMD control effect on the angular displacement and angular acceierauon of the high-rise frame structure under earthquake actions is preferable.
