For the form-finding of complex tensegrity structures, such as tensegrity arches as well as tensegrity towers that are considered in this study, we make use of Dynamic Relaxation Method (DRM) to find their configurations at the self-equilibrium state. DRM has great advantages in dealing with complex structures in a simple way, since neither tangent stiffness matrix nor its inverse is necessary. DRM traces the nodal motions of a tensegrity structure due to the out-of-balance forces, and gradually converges to the self-equilibrated configuration subjected to artificial damping. In this study, a simple tensegrity structure is used to tune the parameters so as to improve the convergence performance of DRM. The tensegrity towers as well as arches are considered as numerical examples to demonstrate that DRM is a highly promising method for form-finding of complex tensegrity structures.
