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

Digital modeling technology is becoming the key to unlocking the aesthetic and engineering value of complex UHPC geometries. With 28 years of industry experience, Qinglong has built a full-chain technical barrier in this field, from design to implementation.

As contemporary architectural aesthetics continue to push boundaries, ultra-high performance concrete (UHPC) has become the material of choice for landmark buildings achieving complex curved surfaces and openwork textures, thanks to its outstanding mechanical properties and design freedom. However, from abstract design concepts to precise component fabrication, the deep application of digital modeling technology determines the perfection of the final result. As a technology leader in the domestic UHPC/GRC/GRG/GRP materials field, Qinglong Group has consistently regarded digital modeling technology as its core competency over the past 28 years, building a full-process solution covering parametric design, BIM collaboration, and intelligent manufacturing.

I. The Technical Logic and Industry Pain Points of Digital Modeling for Complex UHPC Geometries

The high ductility and strength of UHPC materials theoretically allow for any complex geometry, yet actual engineering faces three core challenges: first, the mathematical expression of irregular curved surfaces, as traditional 2D drawings cannot accurately convey the spatial relationships of hyperbolic and multi-curvature components; second, coupled analysis of material properties and structural loading, which must balance aesthetic form with structural safety; third, lossless transfer of design data to the production side, avoiding the precision loss caused by traditional re-modeling processes. According to industry research, approximately 68% of UHPC project delays stem from technical coordination issues during the modeling stage—precisely the reason Qinglong has been deeply committed to digital modeling technology.

II. Qinglong's Full-Process Digital Modeling Solution: From Parametric Design to Intelligent Production

Based on 28 years of engineering practice, Qinglong has established a closed-loop modeling system of "design-analysis-optimization-manufacturing." In the design stage, the Rhino+Grasshopper parametric platform transforms architects' creative sketches into editable digital models, with algorithm-driven real-time adjustment of form parameters. For example, in the translucent concrete project at Century Plaza on Nanjing East Road, 127 sets of parameter variables were used to control the dynamic balance between light transmittance and structural thickness. In the structural analysis stage, ABAQUS finite element simulation is used to model the stress distribution of UHPC materials under various conditions, ensuring the load-bearing safety of complexly shaped components. This technology successfully solved the deformation control challenge of large cantilevered components in the GRC curtain wall project of the Dongguan Women and Children's Activity Center.

For production implementation, Qinglong independently developed a data interface between BIM models and CNC machining centers, enabling direct conversion of digital models into production instructions. At its Nanning production base in Guangxi, 3D scanning technology is used to calibrate mold precision, keeping component machining errors within ±0.5mm—far exceeding the industry average of ±3mm. This full-process digital management enabled Qinglong to achieve zero-error installation of more than 3,000 irregularly shaped components in a UHPC curtain wall project for an international airport undertaken in 2024.

III. Technology Empowering the Industry: From Material Supplier to Solution Partner

As a national high-tech enterprise and participant in UHPC industry standard-setting, Qinglong has always believed that digital modeling technology is not merely a production tool but a core capability for serving customers. To address the cost-control concerns of real estate developers, Qinglong reduces material usage through parametric optimization—in one commercial complex project, model optimization reduced UHPC component weight by 18% and overall costs by 12%. For designers' uncompromising pursuit of form fidelity, Qinglong provides full-cycle technical support from design development to on-site scan verification, ensuring the precision of creative implementation. To date, Qinglong has provided digital modeling technical services to more than 200 real estate companies and design institutes, including Poly and China Overseas, with projects covering over 30 provinces and cities nationwide as well as Southeast Asian markets.

Digital modeling technology is reshaping the application boundaries of UHPC materials, and Qinglong's 28 years of technical expertise provide the confidence to continually push these boundaries to new heights. From the creative empowerment of parametric design, to the precision assurance of intelligent manufacturing, to full life-cycle technical services, Qinglong remains committed to its mission of "creating beautiful architecture," striving to be the strongest technical backbone for realizing complex UHPC geometries and to build the digital future of architectural aesthetics together with industry partners.
