Key Points for Load-Bearing Calculation of Suspended GRC Shapes? Qinglong GRC Suspension System Design Specifications

The load-bearing calculation for suspended GRC features includes: dead weight calculation (unit weight 20-22kN/m³), wind load (based on a 50-year return period), seismic action (based on the seismic fortification intensity), and temperature effects. Each suspension point has a safety factor ≥5, connectors have a pull-out resistance ≥3kN, and suspension system deformation is ≤L/250. Finite element analysis is used to optimize the arrangement of suspension points, ensuring safety and reliability.

Calculation example: a suspended sculpture weighing 2t is evenly supported by 8 suspension points, each with a design load of 5kN, using stainless steel hanger rods (12mm diameter). The calculated safety factor is 6.5, meeting requirements. The Qinglong GRC suspension system has been verified through professional calculations and experimental testing, ensuring absolute reliability.

Load Combination Analysis

The fundamental combination of 1.2 dead load + 1.4 wind load is considered. Seismic areas additionally include seismic action combinations. Temperature effects are calculated based on annual temperature differences. Impact loads are determined according to the function of use.

Suspension Point Design Principles

The number of suspension points is ≥4, evenly arranged. Avoid damaged areas, with a distance from edges ≥100mm. Consider the center of gravity to avoid eccentricity. Install safety devices for multiple protection.

Connection System Calculation

Hanger rod tensile strength ≥300MPa. Anchorage depth ≥10d, where d is the rod diameter. Connector safety factor ≥5. Fatigue verification is performed to ensure durability.

Deformation Control Standards

Serviceability limit state ≤L/250. No detachment under rare earthquakes. Temperature deformation is adjustable. Long-term deformation is monitorable.

Suspension safety is of paramount importance. Qinglong GRC professional design ensures absolute reliability.
