Research on Digital Modeling Process and Key Technologies for Complex UHPC Shapes

UHPC Form Innovation Driven by Digital Technology: Full-Chain Breakthrough from Design to Realization

Driven by both contemporary architectural aesthetics and engineering technology, Ultra-High Performance Concrete (UHPC) is becoming the core material for shaping architectural skin art with its outstanding mechanical properties and design freedom. However, in the process of realizing complex UHPC forms from conceptual design to physical presentation, the in-depth application of digital modeling technology has become the key factor determining project success. As an industry practitioner with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group has built a complete solution from parametric design to intelligent construction within its digital modeling process through full-chain technology integration, providing a technical paradigm for designers and owners to overcome the challenges of realizing complex forms.

Technical Logic and Process Reconstruction of Digital Modeling for Complex UHPC Forms

Digital modeling of complex UHPC forms requires breaking through the linear design thinking of traditional concrete components and establishing a closed-loop system of "parametric drive - performance optimization - intelligent manufacturing." In the translucent concrete project of the Nanjing East Road Century Plaza renovation, Qinglong's technical team built a double-curved parametric model using the Rhino and Grasshopper platforms, converting designers' hand-drawn curves into quantifiable mathematical equations and achieving form accuracy within ±2mm. This process includes three core stages: first, form analysis, using 3D laser scanning technology to digitally reconstruct the design scheme and generate a composite model containing material properties and structural loads; second, performance simulation, using ABAQUS software to conduct UHPC material flow simulation and structural load-bearing analysis to optimize reinforcement schemes and casting paths; finally, data delivery, converting model information into CNC machining instructions to directly drive mold carving and component production, achieving seamless "design-production" data connection.

Key Technical Breakthroughs: Tackling Challenges from Form Art to Engineering Realization

In the process of realizing complex UHPC forms, digital modeling needs to solve three major technical bottlenecks. The first is precision control of irregular curved surfaces. Qinglong's self-developed "multi-point positioning compensation algorithm" sets dynamic adjustment nodes in mold processing, controlling the jointing error of double-curved components within an industry-leading 1.5mm; this technology has been successfully applied in the GRC project of the Dongguan Women and Children's Activity Center. The second is balancing material performance with form complexity. By introducing topology optimization algorithms, the team reduced material usage by 30% while ensuring structural safety, and adopted basalt fiber dosage optimization technology to increase the flexural strength of UHPC components to above 22MPa. The third is digital collaborative management. Relying on a BIM platform to integrate full-process data covering detailed design, production scheduling, and construction installation, it achieved zero-error installation of a 5,000㎡ UHPC curtain wall in a commercial complex project in Nanning, shortening the construction period by 40% compared with traditional processes.

Industry Value Reconstruction: Digital Modeling Empowering the Expansion of UHPC Application Boundaries

The maturity of digital modeling technology is reshaping the application ecosystem of UHPC materials. For real estate developers and construction company decision-makers, the cost controllability brought by parametric design (reducing overall costs by 25% compared with traditional irregular components) and construction schedule assurance make them more competitive in high-end commercial complexes and landmark buildings. For architects, Qinglong's integrated "design-material-construction" digital solution compresses the creative realization cycle from the traditional 3 months to 45 days; for example, in a GRG ceiling project at an international airport, digital pre-assembly technology solved the installation challenge of 12m-span curved surfaces. As a national high-tech enterprise and a participant in UHPC industry standard formulation, Qinglong is extending UHPC application scenarios from architectural skin to landscape sculptures, bridge components, and other fields through digital technology. In its overseas project in Malaysia, a translucent UHPC landscape pavilion realized with digital modeling technology has become a local cultural landmark.

Amid the wave of integrating building industrialization with digitalization, digital modeling of complex UHPC forms is no longer just a technical means but a core engine reshaping architectural aesthetics and engineering efficiency. Building on 28 years of full-chain experience, Qinglong Group continues to drive UHPC materials from "moldable" to "precisely controllable" through the technical closed loop of parametric design, performance simulation, and intelligent construction. In the future, with the deep integration of AI-generated design and digital twin technology, UHPC will unleash its form potential in more landmark projects, and enterprises mastering core digital modeling technologies will become the leaders of innovation in the architectural decorative materials field.
