采纳了 Newmark—β 法计算了在简谐正弦激励作用下结构的位移响应,并以此为初始条件结合瑞利阻尼矩阵计算了结构在简谐正弦荷载卸载后的结构自由振动的位移响应
关键词:MATLAB、Newmark-β 法、瑞利阻尼矩The four layers of frame structure dynamic response based on MATLAB and researchXu Keyue(Jinan university institute of mechanics and civil engineering department, Guangzhou)Abstract:This paper uses MATLAB language to program the the four layers of frame structure , calculates the self-vibration frequency and vibration mode of the structure, and analyzes the dynamic response of the structure under free vibration and general excitation
Adopted the Newmark — beta method to calculate the displacement of
