What Is the Typical Thickness of GRC Panels for Curtain Walls? Analysis of Qinglong GRC Panel Thickness Design Standards

The thickness design of GRC panels for curtain walls requires comprehensive consideration of strength, stiffness, construction details, and economy, typically ranging from 15-30mm. Based on extensive engineering practice, Qinglong GRC has developed a scientific panel thickness design method.

In a 200-meter super high-rise project in Shenzhen, Qinglong GRC optimized panel thickness through finite element analysis: 20mm in standard areas, 25mm in reinforced areas, and 30mm at corner sections. This differentiated design saved 20% in materials while meeting mechanical requirements. Verified by wind tunnel testing, under a once-in-a-century wind pressure, the maximum panel deflection was ≤L/200, fully satisfying code requirements.

Strength-Controlled Thickness Design

Calculate bending moments based on wind loads and determine panel thickness with flexural strength ≥18MPa; account for impact loads with a panel thickness ≥15mm; increase safety factors at critical locations. Strength control is the basic requirement.

Stiffness-Controlled Thickness Design

Control panel thickness by deflection ≤L/200; large panels require increased thickness or stiffening ribs; double-curved panels can be appropriately thinned. Stiffness control affects functionality.

Thickness Determination by Construction Requirements

Embedded parts require panel thickness ≥20mm; insulation layer installation requires panel thickness ≥18mm; special shapes are determined by the fabrication process. Construction requirements must be comprehensively considered.

Economic Optimization Design

Reduce panel thickness through optimized panel layout; adopt stiffening ribs for local reinforcement; implement differentiated thickness design. Economic optimization lowers costs.

Panel thickness design requires comprehensive consideration. Detailed calculations are recommended to select the optimal solution. Qinglong GRC provides professional panel thickness design services to ensure both safety and economy.
