ABSTRACT
Sina Nabaei, PhD, Olivier Baverel, PhD, and Yves Weinand, director of IBOIS, present a novel approach for simulating and analysing such structures that hybridises physics-based form-finding methods borrowed from computer graphics, the structural logic of reciprocal structures, textile inspired interlacing of structural members, and rigorous Finite Element Analysis. The result is a custom simulation and analysis workflow that takes the non-linearity of the simulation problem into account, while at the same time simplifying the structural simulation and analysis. This chapter presents two physics-based models, respectively introduced for thin rod and thin plate simulation, and integrates them into a hybrid form-finding pipeline for timber fabric structures. The hybrid approach takes advantage of both kinematic models, and both simulation frameworks depending on the physical problem to simulate. Intersection detection is advantageous because of its plate kinematics in a dynamic simulation, where the information about the vertex trajectory is available. This motivates a hybrid approach, taking advantage of both rod and plate models.
