| 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. |
