How to Analyze Force Flow Distribution in Hyperbolic GRC Shapes?

In contemporary architectural design, double-curved GRC forms have become the "finishing touch" of landmark buildings with their unique curved aesthetics and structural expressiveness. However, their complex geometric shapes also place extremely high demands on force flow distribution analysis. As an industry leader with 28 years of experience in in-depth design and engineering of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the force flow distribution optimization path for double-curved GRC forms from three dimensions—material properties, structural simulation, and engineering practice—providing professional solutions for designers and owners.

### I. Material Properties of Double-Curved GRC: The "Innate Genes" of Force Flow Distribution

The force flow distribution analysis of double-curved GRC (Glass Fiber Reinforced Concrete) must first be grounded in the essence of the material. Compared with traditional concrete, GRC increases flexural strength to over 20MPa through the combination of glass fibers and cement matrix, while weighing only 1/4 of natural stone, laying a material foundation for force flow transfer in curved structures. In material formulation R&D, Qinglong Group adjusts fiber content (typically 4-5%) and matrix proportions to give double-curved GRC components both rigidity and toughness, effectively dispersing stress concentrations caused by curvature changes. For example, in the Dongguan Women and Children's Activity Center project, the double-curved GRC curtain wall panels, through material optimization, successfully kept bending stress caused by dead loads within 85% of the design limit, verifying the positive impact of materials on force flow distribution.

### II. Parametric Design and Structural Simulation: The "Digital Engine" of Force Flow Visualization

The force flow distribution analysis of double-curved GRC forms relies on the support of digital tools. Qinglong Group uses the Rhino+Grasshopper parametric platform to convert architectural curved surfaces into computable geometric models, combined with ANSYS finite element simulation software, to achieve visual simulation of force flow paths. The specific process includes: first, establishing NURBS surface models of the double-curved surfaces, meshing the elements and assigning GRC material properties; second, applying boundary conditions such as wind loads, dead loads, and temperature loads to simulate stress contour maps under different working conditions; finally, optimizing reinforcement schemes and anchoring joint designs based on force flow concentration zones. Taking the Nanjing East Road Century Plaza renovation project as an example, simulation analysis of its translucent concrete double-curved components revealed that the concave parts of the surfaces are prone to tensile stress concentration. By locally increasing fiber mesh density and adding hidden beams, the force flow transfer paths became more reasonable, ensuring structural safety.

### III. Force Flow Optimization in Engineering Practice: Full-Chain Control from Design to Installation

Theoretical analysis must be closely integrated with engineering practice. In double-curved GRC projects, Qinglong Group achieves force flow distribution optimization through full-chain control of "design-production-installation." In the detailed design phase, BIM technology is used for clash detection to avoid force flow interruptions caused by misaligned component joints; in production, 3D scanning technology is introduced to ensure forming accuracy errors of double-curved components are ≤3mm, providing a geometric basis for uniform force flow transfer; during installation, modular hoisting and laser positioning are used to ensure load transfer between components meets design expectations. Taking a commercial complex double-curved GRC sunshade panel project as an example, by optimizing support spacing and connector stiffness, the torque generated by wind loads was dispersed across the entire support system, with measured maximum stress values 22% lower than traditional installation methods, fully demonstrating the regulatory role of construction techniques on force flow distribution.
