Analysis of Equilibrium and Carrying Capability of the Octahedral Truss Structure

Abstract:

The truss structure has characteristics of small mass with high rigidity etc., so it is still practical in structures and researched by engineers and scientists. Here a truss structure with the paraboloid top surface is presented; several truss forms of the octahedral space units are connected into it. The equilibrium matrix is calculated by the force-density method. From the equilibrium matrix, number of the self-stress mode and number of the displacement mode of the structure is calculated. According to the obtained result, the structure is proved to be in equilibrium. Through the ANSYS software, the truss structure is researched for deformation under outer forces and it is proved that the structure has certain rigidity and withholding capacity.
