Effect of Truss Number on the Dynamic Response of Truss

The safety of truss is determined by dynamic response of truss during the engineering application. Truss number is an important parameter for the engineering application of truss, which is related with the economy and convenience. The effect of truss number on the dynamic response of truss can be analyzed by means of commercial finite element software. Here, a finite element model (FEM) was employed to simulate the dynamic response of truss structure. By using the proposed FEM, the effects of truss number on the maximum displacement and Mises stress were researched. Based on the numerical results, the dynamic responses are different from each other for different truss numbers. The maximum displacement and Mises stress increase with the increasing truss number; however, the maximum displacement and Mises stress keep on a stable value when truss number is more than a certain number.
