确定杆件重要性系数的能量方法
The energy method to define the import coefficient of members
【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。
【Abstract】 This paper bases on the energy theory,defines two formulas of import coefficient of members.And the finite element 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.
