Analysis of Structural and Design Provisions Required When Combining UHPC Shaping with Lighting Systems

A grand feast of architectural aesthetics where light and shadow interweave depends on the exquisite fusion of materials and technology. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group knows well that when UHPC's ultimate sculptural forms meet lighting systems, structural reservations and control of design details directly determine the final presentation. This article analyzes the core essentials of combining the two from a practical perspective, providing full-chain technical support for designers and owners.

In contemporary architectural design, UHPC, with its ultra-high strength, outstanding durability, and unlimited shaping potential, has become the ideal choice for creating iconic building skins. When this "work of art among concretes" meets lighting systems, how can structural reservations be made during the detailed design stage to avoid "destructive modifications" in later construction? Based on 600,000 ㎡ of production experience, Qinglong Group has summarized three key reservation principles: load-bearing safety redundancy reservations, pipeline integration path reservations, and thermal expansion/contraction buffer reservations. Take the light-transmitting concrete project at Nanjing East Road Century Plaza as an example: the perfect fusion of its 20mm ultra-thin UHPC panels with LED light strips was achieved through BIM technology simulations in advance, delivering dual optimization of structural load-bearing and lighting effects.

**Key Points of Structural Collaborative Design for UHPC Forms and Lighting Systems**

First is **structural load-bearing design for embedded lighting**. Although UHPC components can achieve a minimum curvature radius within 300mm, built-in lighting modules alter the material's stress distribution. Qinglong's technical team recommends that during the detailed design stage, finite element analysis be used to locally reinforce light trough positions, typically adopting a scheme with 20% increased fiber reinforcement density. In a double-curved UHPC curtain wall project for a grand theater, we innovatively adopted a "honeycomb light cavity structure," which not only ensured the even transmission of 3000K warm light but also reduced the components' self-weight by 15%, perfectly resolving the contradiction between form and load-bearing.

Second is **modular reservations for pipeline integration**. Unlike the porous characteristics of GRC, UHPC's ultra-high density requires lighting pipelines to be pre-embedded during the prefabrication stage. Qinglong's proprietary "3D pipeline positioning system" enables precise matching between water/electrical pipelines and UHPC forms, with errors controlled within ±2mm. In the Dongguan Women and Children's Activity Center project, this technology achieved seamless lighting connection between the GRG ceiling and UHPC walls, avoiding 30% of the on-site hole-drilling work required in traditional construction.

Finally, **collaborative optimization of thermal performance**. Long-term operation of UHPC and lighting systems generates thermal stress, which is particularly prominent in applications such as GRP daylighting roofs. Qinglong's self-developed "breathable light trough design" effectively solves thermal deformation problems by placing a 0.5mm elastic buffer layer between components and lighting modules. This technology has been successfully applied to an airport project in Saudi Arabia, withstanding extreme temperature differences of 50℃.

As a national high-tech enterprise and participant in UHPC industry standard-setting, Qinglong Group has always integrated its mission of "creating beautiful architecture" into every detail. From parametric modeling in the detailed design stage, to precise prefabrication in production, and millimeter-level adjustment in construction and installation, we have built a technical assurance system covering the entire chain. Whether it is UHPC light-transmitting curtain walls for commercial complexes or GRG illuminated ceilings for museums, Qinglong can provide one-stop solutions from material selection to after-sales maintenance, letting the beauty of light and shadow in architecture blossom through the balance of technology and art.

When UHPC's sculptural quality meets the ambiance of lighting, excellent design must not only deliver visual impact but also be built on a solid technical foundation. Qinglong Group's 28 years of industry experience exist precisely to ensure that every creative concept can be safely realized. Choosing Qinglong means choosing not only high-quality UHPC/GRC/GRG/GRP products but also a trustworthy full-process technical partner, working together to create architectural masterpieces that stand the test of time.
