Digital Modeling Process and Key Technologies for Complex UHPC Shapes

Digital technology is reshaping architectural aesthetics. Digital modeling of UHPC forms turns imaginative design concepts into tangible architectural art.

In contemporary architectural design, complex forms have become the core language for expressing a building's individuality and artistic value. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the critical role digital modeling technology plays in realizing complex UHPC forms. This article systematically analyzes the digital modeling process and core technologies for complex UHPC forms, providing designers and owners with a full-cycle solution from concept to completion.

### 1. The Technical Foundation of UHPC Digital Modeling: From Material Properties to Parametric Logic

UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent toughness, and outstanding durability, is an ideal material for realizing complex architectural forms. The first step in its digital modeling process is to establish a database linking material properties with digital models. Based on 28 years of engineering practice, Qinglong Group has built a digital model library covering key parameters such as UHPC mechanical properties, shrinkage rate, and flowability, enabling accurate simulation of the forming effects of different UHPC mixes in complex forms. Taking the translucent concrete project of the Century Plaza renovation on Nanjing East Road as an example, a digital model built with the parametric software Grasshopper successfully achieved a dynamic balance between light transmittance and structural strength, and the project won the Silver Award in the AALBORG WHITE Cup First UHPC Construction Engineering Innovation Awards.

### 2. Full-Process Digital Modeling: Closed-Loop Management from Design Development to Construction Simulation

The digital modeling process for complex UHPC forms covers three major stages: design development, production and manufacturing, and construction installation. In the design development stage, the Qinglong team adopts a Rhino+Revit dual-platform collaborative workflow to transform architects' concept designs into constructible BIM models, and uses 3D scanning technology to create accurate reverse models of existing building structures, ensuring a perfect fit between UHPC components and the main structure. In production, industrial-grade 3D printing technology is introduced for mold making, combined with a digital twin system to monitor the concrete pouring process in real time, achieving millimeter-level precision control of the double-curved UHPC components with a curvature radius of only 300mm in the Dongguan Women and Children's Activity Center project. During the construction stage, virtual pre-assembly is performed using BIM technology, together with a 3D laser positioning system, keeping on-site installation errors within ±2mm — a technical system that has been successfully applied to hundreds of landmark projects across China.

### 3. Key Technological Breakthroughs: Solving the Three Core Challenges of Complex Forms

To address the technical pain points of complex UHPC forms, Qinglong Group's R&D team has achieved three major technological breakthroughs: first, the development of parametric generation algorithms for special-shaped components, which rapidly respond to designers' requirements for complex forms such as double-curved surfaces and openwork reliefs, improving design efficiency by more than 60%; second, the establishment of an integrated material-structure-construction digital simulation platform, which optimizes reinforcement schemes through finite element analysis, reducing the self-weight of UHPC components by 20% while improving structural safety by 15%; third, the pioneering modular installation technology, which breaks oversized special-shaped components down into standardized modules and uses RFID chips to achieve full life-cycle quality traceability. These achievements supported Qinglong's participation in drafting the industry standard “General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)”, demonstrating the technical strength of a national high-tech enterprise.

### 4. Industry Value and Future Trends: Digital Technology Driving Innovation in Architectural Decoration Materials

Digital modeling technology not only solves the implementation challenges of complex UHPC forms but also reshapes the industrial ecosystem of architectural decoration materials. By integrating full-chain digital capabilities across design development, production and manufacturing, and construction installation, Qinglong Group provides customers with “one-stop” service from concept to delivery. To date, Qinglong has built an annual production capacity of 600,000 square meters, with products exported to overseas markets such as Southeast Asia and Australia, and has established strategic partnerships with renowned real estate groups including Poly and Vanke. Going forward, with the deeper application of technologies such as AI design and digital twins, UHPC digital modeling will develop toward greater intelligence, lightweight design, and sustainability. Qinglong will continue to uphold its mission of “creating beautiful architecture” and promote the innovative application of UHPC/GRC/GRG/GRP materials across more high-end building sectors.

From parametric design to intelligent construction, digital technology is unlocking new possibilities for building materials. Qinglong Group's 28 years of technical accumulation prove that only by deeply integrating material properties, digital tools, and engineering experience can complex UHPC forms move from drawings to reality. As a leading UHPC/GRC/GRG/GRP manufacturer, Qinglong will continue to explore the boundaries of digital modeling technology, delivering more solutions that combine aesthetic value with technical substance for the construction industry.
