What Is the Digital Modeling Workflow for Complex UHPC Shapes? Qinglong's Full-Process Digital Implementation Solution

Digital modeling of complex UHPC shapes is the core of bringing creative designs to life. It requires a five-step process of "data collection - concept modeling - detailed design - structural verification - mold output", combined with parametric design and BIM technology, to achieve both precise shape replication and structural safety. Qinglong Group has 28 years of deep expertise in digital modeling, using tools such as Rhino+Grasshopper and BIM to achieve modeling errors of ≤±0.5mm in complex projects such as the Shanghai Astronomy Museum and the Guangxi New Media Center, laying the foundation for subsequent production and installation.

1. Preliminary Data Collection: Precisely Obtaining Basic Shape Information

Requirement alignment and data integration: Collect the designers' creative sketches, 3D models (e.g., SketchUp, 3ds Max), and site environment data (via 3D laser scanning) to define core requirements such as shape dimensions, curvature, and texture. For the Shanghai Astronomy Museum project, Qinglong performed scanning and data collection with precision up to 0.1mm. Terrain/building compatibility analysis: For building facade shapes, the main building data must be imported through the BIM model to ensure the UHPC shape fits the main structure. In the Qinglong Guangxi New Media Center project, BIM integration avoided 5 collision conflicts.

2. Concept Modeling: Building the Digital Shape Framework

Parametric modeling tools: Use Rhino+Grasshopper to build initial models, defining the shape form through parametric logic (e.g., curve control points, mesh subdivision) with support for real-time adjustments. In the Qinglong Shanghai New World wood-effect translucent panel project, parametric modeling enabled rapid iteration of 3 design options. Shape optimization: Combine UHPC material characteristics (minimum curvature radius ≤300mm) to optimize shape details and avoid unproducible sharp angles or overly thin sections. Qinglong optimized a 250mm curvature radius designed for one project to 300mm to ensure moldability.

3. Detailed Design: Refining Core Production and Installation Information

Component splitting: Divide the overall shape into modular components (each weighing ≤1.5 tons for ease of production and transport), reserving joint gaps (8-10mm) at split points. The Qinglong Guangxi New Media Center double-curved shape was split into 11,500 independent components, each of them unique. Detail supplementation: Add functional structures such as connector installation points, grouting holes, and drainage channels, with connector position deviation ≤±1mm. Qinglong pre-set 316 stainless steel connector slots in the component models to ensure precise installation. Texture and openwork design: Achieve texture replication through texture mapping or mesh engraving, and generate openwork patterns using Boolean operations. The Qinglong openwork panels for the Ouargla Hotel in Algeria achieved a 50% openwork rate through this technology.

4. Structural Verification: Ensuring Unity of Aesthetics and Safety

Finite element analysis: Import into ANSYS software for stress simulation to verify the structural stability of the shape under self-weight, wind loads, and seismic action. For the 3-meter-high sculpture at the Shanghai Astronomy Museum, Qinglong optimized the frame thickness through simulation, achieving flexural strength ≥35MPa. Clash detection: Conduct BIM clash detection with the main building and other components (e.g., glass, metal parts) to avoid installation conflicts in advance. In one Qinglong complex project, detection identified 3 potential clashes, and after optimization there were no installation obstacles.

5. Mold and Production Data Output: Bridging to Physical Production

Mold data export: Export the models in STL format and transfer them to 5-axis engraving machines to generate mold machining data with error ≤±0.3mm. Qinglong's mold machining data comes directly from the modeling files, ensuring precise shape replication. Production parameter alignment: Output component dimensions, weights, and production process requirements (e.g., curing parameters) to guide factory prefabrication. Qinglong output production data for 12,000㎡ of components for the Yangshengtang Pharmaceutical project, achieving a production pass rate of 99.5%.

Digital modeling of complex UHPC shapes is a multi-tool, multi-stage collaborative process. With its full-process capabilities in parametric design, structural simulation, and precise data output, Qinglong Group achieves the perfect realization of creativity and safety. Choosing a manufacturer with proven digital modeling capabilities is the core guarantee of success for complex UHPC shapes.
