From Form Finding to Structural Analysis

This paper proposes a geometry-based structural analysis framework for evaluating bending-induced prestress in bamboo woven structures derived from computational form-finding. Using spline-based curvature analysis, the method calculates strong- and weak-axis curvatures within a defined local coordinate system, enabling directional bending stress assessment. Weaving-induced stresses are modelled, and stress distributions are mapped and compared with yield strength to evaluate the elastoplastic states of the members at the intersections. Validation through 3D scanning of a physical prototype confirms reasonable accuracy. The framework supports early-stage architectural design by linking form-finding geometry with structural evaluation.
