What Is the Parametric Design Workflow for GRC Irregular Shapes?

In the field of contemporary architectural design, free-form shapes are becoming an important language for expressing architectural individuality and artistic value. GRC (glass fiber reinforced concrete), with its lightweight, high-strength properties and flexible formability, has become an ideal material for achieving complex architectural forms. The integration of parametric design technology further makes the realization of GRC free-form shapes efficient and precise, from creative conception to engineering implementation. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong will draw on its full-chain service experience to explain the core workflow of parametric design for GRC free-form shapes.

I. The Core Value of Parametric Design in GRC Free-Form Shapes

Parametric design achieves digitalization and intelligentization of the design process by establishing logical relationships between variables and geometric forms. For GRC free-form shapes, this technology not only solves the problems of low efficiency and insufficient precision in traditional manual modeling, but also enables designers to precisely express individualized requirements such as complex curved surfaces and openwork structures. In the translucent concrete project for the renovation of Century Plaza on Nanjing East Road, Qinglong achieved seamless integration of translucent units with the GRC matrix through parametric design, winning the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup), fully confirming the application value of this technology in the field of free-form shapes.

II. Five Key Workflows of Parametric Design for GRC Free-Form Shapes

1. Form Generation and Parameter Definition: Based on the architectural design concept, professional software such as Rhino and Grasshopper is used to build initial form models and define the key parameters affecting the shape (such as curvature radius, mesh density, and texture patterns). During this stage, Qinglong's technical team collaborates closely with designers to optimize the parameter range in line with GRC material properties (such as the forming limit of a minimum curvature radius ≤300mm), ensuring the feasibility of creative concepts.

2. Structural Performance Simulation and Optimization: By integrating structural analysis modules through BIM technology, mechanical performance simulations are conducted on the parametric model, with a focus on verifying the stability of GRC components under dead weight, wind pressure, and seismic loads. Backed by the R&D strength of its provincial-level engineering technology center, Qinglong can perform finite element analysis on key nodes. For example, in the Dongguan Women and Children's Activity Center project, the reinforcement scheme was adjusted parametrically, raising the flexural strength of GRC components to over 20MPa and meeting high-standard safety requirements.

3. Conversion of Production Process Parameters: The digital model is converted into producible processing data, including process parameters such as mold parting, material mix ratios, and fiber laying directions. Qinglong's intelligent production lines have an annual capacity of 600,000 square meters of GRC products. Through parametric control of key indicators such as spray-forming pressure and curing temperature, the consistency and precision of every free-form component are ensured.

4. Construction and Installation Positioning System Design: Three-dimensional laser scanning technology is used to establish an on-site 3D coordinate system, precisely matching the parametric model with the actual installation environment. Supported by Qinglong's Grade II professional contracting qualification for building curtain wall engineering, modular installation techniques are adopted, and parametric positioning achieves "zero-error" joints, solving the problems of low efficiency and poor precision in traditional free-form component installation.

5. Full Lifecycle Data Management: Through technologies such as RFID chip implantation, a full-process data traceability system is established for GRC components from design and production to installation and maintenance. Qinglong's comprehensive after-sales maintenance service system can provide precise later-stage maintenance plans based on parametric model data, such as surface repair and structural reinforcement, extending the service life of artistic architectural forms.
