| Abstract: | In this papre, the modified element stiffness matrix of the structures without sidesway is presented, including the acting of local inertial force of the element. The numerical results in the paper show that the modified element is used to analyse the free vibration, and the accuracy of the structural frequency is greatly raised at no increasing the freedom. |
