Abstract

In view of vibration models of high-rise buildings with podium, on the basis of analyzing its structural equation of motion, it applies the fuzzy control algorithm to control simulation on high-rise buildings models with 12-storey main building and 3-storey podiums, that is using the fuzzy control strategy to control the force output of semi-active control device of MR damper. The fuzzy control as a branch of intelligent controls can well and proficiently bring operators' subjective experience and intuition into the control system, and it analyzes and synthesizes the system from the point of features of the system and the overall optimization. It simulates the displacement of top storey and velocity & time-histories curve, and obtain damped percentage through the comparison of results without control, with evident result.
高层建筑结构振动模糊控制算法研究
针对带裙楼高层建筑的振动模型,在分析裙楼结构运动方程的基础上,将模糊控制算法应用于12层主楼和3层裙楼高层建筑模型的控制仿真,即利用模糊控制策略控制MR阻尼器半主动控制装置的力输出。模糊控制作为智能控制的一个分支,能很好、熟练地将操作者的主观经验和直觉融入到控制系统中,从系统的特点和整体优化的角度对系统进行分析和综合。对顶板位移和速度时程曲线进行了模拟,并与不加控制的结果进行了对比,得到了阻尼百分比,结果明显。
