How to Analyze Force Flow Distribution in Double-Curved GRC Forms?

Force flow analysis of double-curved GRC shapes is performed using finite element software, taking into account the coupling effect of in-plane stress and out-of-plane bending. Qinglong Group uses ANSYS software with a mesh size ≤20mm to accurately simulate complex stress states.

Boundary conditions are realistically simulated. Constraints are set according to actual connection methods, and loads are based on the most unfavorable combinations. In the roof analysis of the Hainan Convention and Exhibition Center, stress concentration was identified in the edge areas; by adding stiffening ribs, stress was reduced by 40%. Force flow paths are visualized to optimize fiber orientation and improve material utilization.

The results guide structural detailing. Stiffening ribs are arranged according to stress contour maps, with local reinforcement in critical areas. Through form-finding analysis, surface curvature is optimized to achieve a more uniform force flow distribution. This scientific analysis ensures that double-curved shapes are safe and reliable.
