Research on Force Flow Distribution Analysis Method and Engineering Application of Double-Curved GRC Forms

The vitality of architecture lies in the balance between strength and beauty. When double-curved GRC outlines a building's skyline with its graceful, flowing curves, the hidden law of force flow distribution behind it is the key to achieving a harmonious unity of artistic form and structural safety. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group has always taken "creating beautiful architecture" as its mission, exploring the deep integration of materials science and architectural art through the force flow analysis and engineering practice of double-curved GRC forms.

Force Flow Distribution in Double-Curved GRC: Key Breakthroughs from Mechanical Principles to Form Realization

Double-curved GRC forms, with their continuously varying curved surfaces, visually endow buildings with strong dynamism and tension, but they also pose stringent challenges to material performance and structural design. Force flow distribution analysis—the precise calculation of stress transfer paths at each point of the curved surface to ensure the material's load balance under dead weight, wind loads, and temperature effects—is the core step for double-curved GRC to move from conceptual design to engineering implementation. Relying on the technical accumulation of its provincial-level R&D center and engineering technology center, and drawing on more than 20 years of experience participating in the formulation of industry standards such as the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong Group has developed a full-process force flow solution covering parametric modeling, finite element analysis, and node optimization.

Full-Chain Technical Support: Qinglong's Advantages in Double-Curved GRC Engineering Applications

The successful application of double-curved GRC depends on full-chain capabilities ranging from detailed design to after-sales maintenance. In the design phase, the Qinglong team uses the Rhino+Grasshopper parametric platform to translate architectural aesthetic requirements into quantifiable force flow models, achieving collaborative optimization with structural, MEP, and other disciplines through BIM technology. In production, relying on the 600,000-square-meter annual capacity of its production base in Nanning, Guangxi, automated spray molding and steam curing processes ensure the uniform fiber distribution and strength stability of double-curved components. In construction and installation, the combination of 3D laser scanning and modular hoisting technology achieves "zero-error" assembly of complex curved surfaces. For example, in the Century Plaza renovation project on Nanjing East Road, Qinglong's force flow optimization solution for its translucent UHPC components won the Silver Award at the first AALBORG WHITE Cup UHPC Building Engineering Innovation Awards.

Solving Industry Pain Points: From Technical Empowerment to Value Creation

Currently, double-curved GRC still faces pain points in engineering applications, such as high costs of form realization and difficulty in verifying structural safety. Addressing designers' core need for "balancing complex forms with structural safety," Qinglong provides solutions through the following approaches: First, establishing a force flow database based on 58 patented technologies and over a thousand engineering projects, offering standardized force flow analysis templates for double-curved forms of varying curvature and span. Second, innovating material formulations by adjusting glass fiber content and cement-based mix ratios, enabling GRC flexural strength to consistently reach 20MPa or above to meet the load-bearing requirements of large-span double-curved components. Third, providing integrated "design-production-installation" services. For example, in a double-curved ceiling project for a grand theater, the Qinglong team optimized the anchor node design through force flow simulation, controlling installation error within 3mm while reducing material waste by 15%.

From the irregular GRC curtain wall of the Dongguan Women and Children's Activity Center to double-curved landscape components exported to Southeast Asia, Qinglong Group has always upheld the values of "honesty, striving, trust, and collaboration" to drive the innovation and application of double-curved GRC technology. Looking ahead, as UHPC/GRC/GRG/GRP materials continue to expand in the field of architectural decoration, Qinglong will continue to pursue its vision of "becoming an outstanding world-leading manufacturing enterprise," providing designers and owners with double-curved form solutions of greater aesthetic value and technical assurance, so that every curve carries an eternal dialogue between strength and beauty.
