【摘要】 在已有MBC理论基础上考虑结构的非线性变形问题,结合拟力法提出一种结构非线性分析新方法。以MBC控制策略为基础,以拟力法为结构非线性求解平台,解决了结构动力分析中计算时间长、求解速度慢、存储空间大等问题,实现了MBC策略在结构非线性控制领域的应用。以一个9层钢框加结构为算例比较了该方法与LQR算法的控制效果,验证了该方法的正确性和有效性。更多还原

【Abstract】 In this paper,a new method that combines the Market-Based Control(MBC) strategy and Force Analogy Method(FAM) is presented to realize the nonlinear structural vibration control.The MBC is used to reduce the structural vibration response and FAM is proposed to perform the nonlinear analysis,which reduces computation time and storage sqaces,and enhances computing speed.A numerical example of nine-stories steel frame structure is used to compare the control effect of this method and usual LQR algorithm,which shows the accuracy and efficiency of the proposed computation method.更多还原
