摘要
:给出了高度较大的支耳式设备的抗震设计计算的具体方法 :将框架和设备的质量分布进行适当简化 ,建立质点系的动力学方程组。通过对方程组的求解 ,得到这种类型设备的自振周期及振型。质点在各振型中的地震作用及地震弯矩的计算、各计算截面的应力校核等 ,则可采用《钢制塔式容器》JB4 71 0— 1 992标准中所提供的计算方法进行计算。
The specific method of aseismic design calculation for a lug type equipment with a relative large height is given.The mass distributions of fram and equipment are simplified properly,and the dynamic equation groups of mass system are established.By solving equation group,the basic nature vibration period and vibration modes of this type equipment are obtained.The calculations of mass seismic action in every vibration mode,the seismic bending moment,and the stress check of every calculation section etc,may adopt the calculation methods proposed by“steel tower vessel”JB4710-92 standard.
