Factors affecting the design of GRC
Panel structure and basic design principle
GRC mechanical properties and physical and chemical properties design
GRC Product Design
Production process scheme and ratio design
Natural forces: wind, water, heat, earthquake
Other: fire, sound, electrochemical erosion, corrosion, carbonation
Building structure: reinforced concrete frame, steel structure, cast-in-place shear wall, masonry structure
The rigid curved shape is designed and manufactured according to the principle of thin shell structure by making full use of the high flexural, tensile, shear, and impact strength unique to GRC facades materials. It emphasizes the comprehensive use of material mechanics and structural mechanics, combined with the rationality of geometric modeling, and relies on the bi-directional axial force and paraxial shear force within the curved surface to bear the load. Through the change of curved shape, it enriches the decorative effect of the building facade; reduces the self-weight of the structure, uniform internal force, improves the overall workability of the space, high strength, high stiffness, material saving, economic and reasonable.
The performance requirements of GRC concrete vary greatly for different application conditions. It is well known that the wind load differs greatly between coastal areas and urban centers, and between high-rise buildings and low-rise villas. Another example: is roof and wall comparison, the roof conditions are much worse, and ordinary GRC will be difficult to cope with because the roof by rain, freezing, and direct sunlight, GRC materials will produce wet expansion and dry shrinkage, thermal expansion, and contraction, the lack of fatigue resistance of ordinary GRC internal structure will be damaged. Many situations must be considered: rough and smooth surfaces; light and dark colors on the absorption of the heat generated by sunlight
In-depth communication between architects and glass fiber reinforced concrete engineers is essential.
Internal structural design of the product: steel skeleton, reinforcement ribs, hemming.
Structural nodes and structures are to be noted in the fixed system.
Panel construction design

Interface with adjacent materials
After comprehensive consideration of the use of environmental conditions, the functional and performance index system of glass fiber reinforced concrete materials is designed in a targeted manner. Based on these data, the production process and ratio design are developed. Under the condition of satisfying the use conditions, sufficient safety factor is reserved, and various technical process procedures are reasonably used to design a complete technical and economic scheme. Among them, firstly, choose the suitable process route, then choose the matching raw materials, after that, carry out the ratio design, test matching verification, and organize the implementation.
