Research on Force Flow Distribution Analysis Methods and Key Technologies for Double-Curved GRC Shapes

In the field of contemporary architectural design, double-curved GRC shapes have become the "finishing touch" of landmark buildings with their unique artistic expressiveness and structural aesthetics. However, the force flow distribution patterns within their complex curved geometries have long remained a core technical challenge for designers and engineering teams. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has accumulated extensive experience in force flow analysis and key technology application for double-curved GRC shapes through integrated practice in detailed design, manufacturing, and installation, providing the industry with solutions that combine both safety and artistry.

Force Flow Distribution Analysis of Double-Curved GRC Shapes: Breakthroughs from Theory to Practice

The force flow distribution of double-curved GRC components exhibits significant nonlinear characteristics, and traditional linear mechanical analysis can hardly capture their stress transfer paths accurately. Relying on the R&D strength of the provincial engineering technology center, Qinglong's technical team established a three-tier analysis system of "parametric modeling – finite element simulation – physical testing": 1:1 digital models were built on the Rhino and Grasshopper platforms and imported into ABAQUS for multi-load-case simulations, with particular attention to stress concentration in key areas such as abrupt curvature changes and anchoring nodes. In the Dongguan Women and Children's Activity Center project, addressing the bidirectional bending characteristics of the double-curved GRC curtain wall, the team innovatively adopted a "grid discretization" analysis method, decomposing the complex surface into multiple micro-elements for force flow tracing, ultimately achieving installation error control within ±2mm and winning the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award.

Key Technical Innovations: Coordinated Optimization of Materials, Processes, and Installation

Realizing double-curved GRC shapes depends on dual breakthroughs in material performance and process technology. Qinglong's self-developed low-alkalinity GRC formulation, through optimized glass fiber content (5%-6% by volume) and mineral admixture compounding technology, raises the flexural strength of components to 22MPa with an elastic modulus of 28GPa, meeting the load-bearing requirements of complex curved surfaces. In production, the "vacuum infusion + 3D mold" process ensures uniform compaction of concrete within the double-curved mold cavity, with surface flatness errors controlled within 0.5mm/m. To tackle the installation challenges of large double-curved components, the team developed "BIM pre-assembly + laser positioning" technology. In the Nanjing East Road Century Plaza renovation project, they successfully installed a translucent GRC double-curved panel weighing 8 tons with a curvature radius of 3.5 meters, achieving "mirror-level" alignment precision with the glass curtain wall, and the project won the Silver Award of the First UHPC Construction Engineering Innovation Award.

Full-Chain Service Empowerment: Closed-Loop Assurance from Detailed Design to After-Sales Maintenance

As a new-type decorative building materials enterprise, Qinglong has always upheld the mission of "creating beautiful architecture" and built a service system covering the entire life cycle of double-curved GRC shapes. In the design phase, it provides full technical support from scheme optimization to node detailing, helping designers balance artistic creativity with structural safety; production relies on the 600,000-square-meter annual capacity of the Guangxi Nanning production base to enable large-scale delivery of customized components; during construction, modular installation and real-time stress monitoring technologies ensure that force flow transfer paths remain consistent with the design model; in the after-sales phase, a "five-year warranty + lifetime maintenance" mechanism has been established, safeguarding the long-term safety of double-curved GRC shapes through regular inspections and structural health monitoring. This full-chain service model has been successfully applied to overseas projects such as the podium renovation of the Petronas Twin Towers in Kuala Lumpur, Malaysia, and the expansion of the Esplanade Theatres on the Bay in Singapore, becoming the core competitiveness of Qinglong's international branding.
