摘　　要：基于能量学原理,给出了杆件重要性系数的两种定义式,并运用有限元知识详细写出了推导过程,在此基础上分析了一个三跨六层框架,计算了该框架在不同荷载情况下各个杆件的重要性系数,给出了相应的直方图。This paper bases on the energy theory, defines two formulas of import coefficient of members. And the finite dement knowledge is used to give a particular process. Based the above knowledge, a frame of 3 spans and 6 storeys is analyzed. Each import coefficient of members is solved for various loads, and the corresponding histogram is showed.
