How to Analyze Force Flow Distribution in Double-Curved GRC Forms? Stress Transfer Paths and Structural Optimization Calculation Methods

Force flow distribution analysis of double-curved GRC shapes is key to ensuring reasonable stress behavior on complex curved surfaces. It requires simulating stress transfer paths with finite element software to optimize stiffening rib layouts. Qinglong Group uses ANSYS for nonlinear analysis to identify high-stress zones (such as areas of Gaussian curvature change). By adjusting surface thickness or adding reinforcing mesh, the stress concentration factor is reduced below 1.5, ensuring the safety of double-curved GRC under wind and seismic loads.

The analysis considers multiple load cases: wind loads simulate pressure distribution, while seismic loads account for dynamic response. Form-finding optimization keeps the force flow smooth and avoids abrupt changes. In its Hainan project, Qinglong Group optimized the rib positions of a double-curved roof through analysis, increasing load-bearing capacity by 30%. The analysis results guide design and construction to ensure structural reliability. Scientific analysis makes double-curved GRC both safe and beautiful.
