摘要
从框架悬挂结构的自由振动基本方程入手,给出了框架悬挂结构中主体框架结构与悬挂楼层振型分量间的关系,并在悬挂长度及质量比相等的条件下,推导了框架悬挂结构频率计算的理论公式,从理论上对框架悬挂结构的动力特性进行了分析和研究,为进一步研究和分析悬挂结构的动力特性变化规律和减震机理提供了理论基础。
The relationship between the mode of the main structure and that of the suspended floors during free vibration is givenUnder the condition of the equivalence of the suspended length and the mass ratio,the equation for calculating the frequency of frame structure with suspended floors is derivedthe dynamic behavior of the structure is analyzed theorticallyWhich can provide a basis for further researching changing law of dynamic behavior of suspended structure and the mechanism of seismic resistance of such structure[HQ]
