What Is the Role of Load-Bearing Wraps in GRC Components? Structural Reinforcement and Qinglong Group's Design Applications

In GRC components, the load-bearing pack performs three major functions: concentrated load transfer, stress dispersion, and connection reinforcement, enhancing overall load-bearing capacity through local strengthening. In the long-span slabs of the Shenzhen Pingshan High-tech Zone Comprehensive Service Center, Qinglong Group adopted steel-framed load-bearing packs (thickness ≥50mm), raising the flexural strength of the slabs to 25MPa and increasing the span by 30%. Load-bearing pack design must be based on finite element analysis, optimizing shape and position to achieve a balance between safety and economy.

Load Transfer Mechanism

The load-bearing pack converts point loads into surface loads, reducing stress concentration. With Qinglong Group's load-bearing pack design, stress is reduced by 40%.

Material and Process Selection

Steel or high-strength GRC is used to work in coordination with the matrix. Embedded connectors ensure overall integrity.

Application Case Verification

In the Hainan project, load-bearing packs enabled the components to pass the typhoon test. With extensive design experience, they are safe and reliable.

The load-bearing pack is the key to high performance of GRC components.
