How UHPC Hollow Components Ensure Structural Strength in the Openwork Areas? Qinglong UHPC Hollow Component Reinforcement Technology

UHPC perforated components ensure structural strength through optimized perforation rates (≤40%), reinforced frames (width ≥100mm), and local strengthening (thickness increased by 20%). Qinglong UHPC research shows that when the perforation rate is ≤30%, the flexural strength retention rate is ≥85%; when the perforation rate is 40%, stiffening ribs are required.

In detailed design, finite element analysis is used to optimize hole layout and avoid stress concentration; hole spacing is ≥50mm, with 2mm chamfers at hole edges. Shaking table tests show that perforated panels with this design remain intact under seismic intensity 9. A perforated curtain wall (perforation rate 35%) at a cultural center in Shanghai has been in use for 3 years with no cracks.

Perforation Rate Control Standards

Decorative perforation ≤40%; structural perforation ≤25%; these controls ensure strength.

Reinforcement Design Measures

Frame width ≥100mm; local thickness increased by 20%; installation of stiffening ribs; these measures improve stiffness.

Optimized Hole Layout

Avoid stress concentration; spacing ≥50mm; chamfer R2mm; these optimizations reduce stress.

Process Control Key Points

Layer-by-layer casting; enhanced vibration compaction; these controls ensure density.

Perforated components require professional design. Qinglong UHPC offers mature technology—safe and aesthetically pleasing.
