Form-finding of compressive structures using Prescriptive Dynamic Relaxation
We present small strain truss and triangular elements for compressive form-finding. We modify Dynamic Relaxation form-finding to include element prescription. We provide forcing functions to achieve desired segmental geometry. A scheme for equilibrium and geometrical convergence is verified. Case studies validate the practical application of element geometry prescription.
