The present work aims to determine the natural frequencies for a structure with Warren truss by changing the modulus of elasticity to two of the elements of the structure are keeping the same length of the elements. A numerical study is carried out by means of a 3D FE model of a Warren truss, simulating the dynamic interaction of beams with trusses.
Keywords: Warren truss, mode shape, natural frequency
