【摘要】 根据风洞试验结果,深圳京基金融中心横风向响应较大,提出采取AMD振动控制策略控制结构风致响应,以改善结构的舒适度。本文首先依据风洞试验结果,对深圳京基金融中心风振响应进行分析,选取最不利风荷载作为结构的激励荷载;其次,以结构加速度和位移响应作为控制目标,提出了采用控制结构前几阶振型的极点配置法作为AMD振动控制算法;最后,对该控制算法的AMD振动控制效果进行了分析。分析结果表明:AMD对横风向振动控制效果较好,且AMD的各项参数均能满足实际设计要求,采取AMD振动控制措施较大地改善了结构的舒适度。更多还原

【Abstract】 According to the wind tunnel test results,it is obvious for the Shenzhen Kingkey Finance Tower(KFT) response with the across-wind excitations,in order to improve the structural comfortability,the AMD vibration control strategies is proposed to control the structural response.Firstly,the SKFT wind response is analyzed with wind tunnel test results,the wind load is selected to excite the structure with AMD control.Secondly,the pole assignment method with considering the fore-vibration shapes as the control object is adopted for the AMD vibration control algorithm.Finally,the AMD control effect is analyzed.And the results show that AMD control effect is good and the AMD system parameters can be realized.The structural comfortability is improved.更多还原
