Parametric Design Process for GRC Irregular Shapes: Analysis and Practical Application

In contemporary architectural design, the realization of freeform shapes is often the key to expressing a building's artistic value. GRC (Glass Fibre Reinforced Concrete), as a new building material that combines strength and plasticity, provides a systematic solution for bringing complex shapes to life through its parametric design process. As an industry leader with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of the entire parametric design process for GRC freeform shapes, starting from technical logic and practical cases.

The core of parametric design lies in establishing the logical relationship between design parameters and modeling outcomes through digital tools. In GRC freeform components, this process is embodied in a closed-loop system of "3D modeling - performance simulation - production optimization." In the early stage of a project, designers need to build parametric models using software such as Rhino and Grasshopper based on the building's form requirements, generating multiple options for comparison by adjusting variables such as curvature and texture density. In the Dongguan Women and Children's Activity Center project, Qinglong's technical team carried out 12 rounds of parametric iteration to control the minimum curvature radius of the hyperbolic GRC curtain wall within 300mm while satisfying both wind pressure resistance and lightweight self-weight requirements.

The model development stage must focus on balancing material properties with structural safety. Parameters of GRC material such as fiber mix ratio and cement-based strength directly affect the load-bearing capacity of components, so mechanical performance simulation must be carried out in combination with finite element analysis software. Taking the translucent concrete project at Century Square on Nanjing East Road as an example, Qinglong's R&D center optimized the composite ratio of the GRC matrix and translucent materials through parametric simulation, raising the light transmittance of the components by 15% while keeping the bending strength above 22MPa—1.5 times the national "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels" standard.

Parametric control in the production stage is key to ensuring shape accuracy. Qinglong introduced industrial-grade 3D scanning technology at its production base in Nanning, Guangxi, collecting real-time data throughout mold machining and component prefabrication to keep errors within ±2mm. For the complex curved-surface joining of GRG (Glass Fibre Reinforced Gypsum molded products) ceilings, the technical team developed a modular parametric splitting solution that improved installation efficiency by 40%, a technology successfully applied in a provincial-level grand theater project. In addition, by managing the production process parametrically, Qinglong achieved precise scheduling of an annual capacity of 600,000 square meters, ensuring on-time delivery of large projects.

From design to implementation, the parametric process for GRC freeform shapes requires material suppliers with full-chain technical integration capabilities. As a national high-tech enterprise, Qinglong not only participated in formulating the "Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC)" but has also built a complete system from BIM collaborative design to intelligent production through 58 patented technologies. Whether it is the freeform exterior walls of commercial complexes or art sculptures in theme parks, Qinglong can turn creative ideas into reality through parametric design, providing designers and owners with an integrated "technology + aesthetics" solution.

As architectural aesthetics continue to advance, GRC parametric design will become the core technical support for future freeform architecture. With the mission of "creating aesthetically beautiful buildings," Qinglong Group continues to explore the boundaries of integrating material performance with digital technology, striving to become a leader in the UHPC/GRC/GRG/GRP manufacturing field and to provide construction projects worldwide with innovative solutions that combine artistic value and engineering feasibility.
