Role and Application Analysis of Reinforcement Cages in GRC Components

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete) is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its advantages of light weight, high strength, and flexible shaping. As a key component of GRC elements, the design and application of the load-bearing package directly affect the structural safety and durability of the elements. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of the core role of the load-bearing package in GRC elements from the perspectives of technical principles, engineering practice, and industry standards.

### I. Structural Function of the Load-Bearing Package: The "Skeletal System" of GRC Elements

The load-bearing package is a reinforcement structure inside GRC elements used to carry loads, typically composed of steel bars, steel mesh, or fiber composites, forming a coordinated load-bearing system with the GRC matrix. Its main functions include three aspects: first, improving the flexural and shear strength of elements so that GRC remains stable under self-weight, wind loads, and seismic action; second, dispersing stress concentration to prevent cracking caused by excessive local stress; third, optimizing anchorage joint design to ensure a safe connection between the elements and the main building structure. Take, for example, a landmark project Qinglong participated in: by embedding customized load-bearing packages in shaped GRC curtain wall panels, the flexural strength of the elements was increased by 30%, successfully meeting the large-span cantilever design requirements.

### II. Material Selection and Design Key Points of the Load-Bearing Package

The material selection of load-bearing packages must balance strength, durability, and economy. In the detailed design stage, Qinglong typically uses hot-dip galvanized steel mesh or basalt fiber composite bars: the former is suitable for conventional environments, while the latter can improve corrosion resistance by more than 50% in coastal areas with high salt spray. During the design process, parametric modeling must be carried out in combination with element dimensions, load-bearing modes, and installation methods. For example, for Roman column elements of European classical style buildings, the load-bearing package needs to be designed integrally with GRC decorative moldings to ensure a balance between aesthetic appearance and structural safety. In addition, the BIM collaborative design platform developed by Qinglong through its provincial engineering technology center can achieve precise matching between load-bearing packages and GRC elements, with errors controlled within ±2mm.

### III. Application Cases of Load-Bearing Packages in Typical Engineering Scenarios

In actual projects, the application of load-bearing packages needs to be flexibly adjusted according to project characteristics. For the GRC exterior wall cladding panels of commercial complexes, Qinglong adopted a "grid-shaped load-bearing package + lightweight matrix" solution, reducing element weight by 60% compared with traditional stone, while optimizing anchorage point spacing through mechanical simulation to ensure a wind load resistance of 1.5kPa after installation. For small elements such as GRC benches and flower beds in landscape gardens, load-bearing packages mainly adopt concealed designs, replacing traditional steel bars with fiber-reinforced materials, which not only meets load-bearing requirements but also avoids exposed rust affecting aesthetics. It is worth noting that the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong participated in formulating, provides clear specifications for the material performance, design methods, and construction techniques of load-bearing packages, offering a technical reference for the industry.

### IV. Quality Control of Load-Bearing Packages and Industry Trends

As a national high-tech enterprise, Qinglong has established a strict quality control system for load-bearing packages: from incoming raw material inspection (such as tensile strength of steel bars and fiber dispersion), to non-destructive testing during production, and then to load tests before delivery, ensuring that every batch of elements meets the standards. With the development of construction industrialization, load-bearing packages are being upgraded toward modularity and intelligence. For example, the prefabricated load-bearing package components developed by Qinglong can be produced to factory standards and quickly assembled on site, greatly improving construction efficiency. In the future, combined with the ultra-high strength characteristics of UHPC materials, the composite application of load-bearing packages and GRC will further expand the design boundaries of elements, providing more possibilities for creating beautiful buildings.

Although the load-bearing package is an "invisible" component of GRC elements, it is a core factor in ensuring building safety and achieving aesthetics. With 28 years of full-chain experience, Qinglong Group deeply integrates the technological innovation of load-bearing packages with engineering practice, not only providing designers with more flexible creative space, but also delivering high-quality projects to owners that combine safety and durability. In the field of new architectural decoration materials, only by focusing on details and adhering to standards can one establish an industry benchmark in the niche market.
