What Is the Digital Modeling Process for Complex UHPC Shapes? A Guide to Precise Digital Implementation

The core of the digital modeling workflow for complex UHPC shapes is "requirement analysis → parametric modeling → mechanical optimization → BIM collaboration → production adaptation → verification and adjustment". Through digital tools such as Rhino, Grasshopper and ANSYS, it achieves seamless integration between creative design and engineering implementation. With 28 years of digital experience, Qinglong has achieved modeling accuracy of ±0.1mm for projects such as Shanghai New World Plaza and the Shanghai Astronomy Museum.

I. Requirement Analysis and Basic Modeling: Anchoring Core Objectives

Preliminary preparation determines the modeling direction. Requirement breakdown: liaise with designers to clarify design intent, dimensional range, aesthetic requirements and performance indicators (strength, wind load resistance); Qinglong's professional team delivers a "Modeling Requirements Checklist" within 72 hours. Data collection: if a physical prototype exists, 3D laser scanning is used to obtain point cloud data with accuracy up to 0.05mm, and Qinglong processes the scanned data for comparison and correction against design intent. Parametric modeling: using Rhino+Grasshopper software, key parameters such as curvature, thickness and openwork ratio are input to generate the 3D model; Qinglong's modeling supports real-time parameter adjustment, improving modification efficiency by 60%.

II. Mechanical Optimization and BIM Collaboration: Balancing Safety and Adaptability

The optimization stage ensures structural safety and installation feasibility. Mechanical simulation: the model is imported into ANSYS finite element analysis software to simulate load conditions under dead weight, wind loads and seismic action, optimizing cross-sectional dimensions and reinforcement; Qinglong's simulation error is ≤5%, avoiding structural risks in advance. Block optimization: blocks are divided according to production equipment capacity (maximum mold size ≤6m×3m) and hoisting conditions; Qinglong's joint seams after block division remain concealed without affecting the aesthetic effect. BIM collaboration: the model is imported into the BIM system for coordination with building structures, installation nodes and plumbing/electrical pipelines to avoid conflicts; Qinglong's BIM collaboration keeps the on-site rectification rate ≤1%.

III. Production Adaptation and Verification Adjustment: Closed-Loop Implementation

Production adaptation and verification ensure modeling results are implemented. Mold parameter output: mold dimensions, material selection (polyurethane/steel mold) and reinforcement plans are exported based on the 3D model; Qinglong's mold design supports digital machining with accuracy up to ±0.3mm. Trial production verification: 1:1 samples are produced to test shape accuracy and structural performance, and Qinglong's sample inspection pass rate reaches 99%. Parameter adjustment: modeling parameters and mold design are fine-tuned based on sample test results, with Qinglong's adjustment cycle ≤3 days. Project cases: for the wood-effect translucent UHPC shapes at Shanghai New World Plaza, through parametric modeling + BIM collaboration, the modeling error of individual 12㎡ super-large components was ≤0.2mm; for sculptures over 3 meters at the Shanghai Astronomy Museum, flexural strength reached 20MPa after mechanical optimization, perfectly balancing aesthetics and safety.
