Material Characteristics and Properties
Steel Properties

High Strength: Steel has high tensile and compressive strength, enabling it to bear significant loads.

Lightweight: Compared to concrete structures, steel structures are lighter, reducing the burden on the foundation.

Ductility: Steel is easy to shape into various forms, meeting complex architectural design requirements.

Corrosion Resistance: Through surface treatments (e.g., galvanization, painting), steel can effectively resist corrosion.

Fire Resistance: Steel loses strength at high temperatures, requiring fireproof coatings or boards for protection.

Structural Features

Modular Design: Steel structure warehouses use prefabricated components, enabling quick assembly and disassembly.

Large Span Design: The high strength of steel allows for large-span designs, providing more internal space.

Seismic Performance: Steel’s good ductility allows it to absorb energy during earthquakes, reducing structural damage.

Environmental Friendliness: Steel is recyclable, reducing construction waste and aligning with sustainable development principles.

Application Advantages

Fast Construction: Prefabricated components are factory-produced, and on-site installation is highly efficient.

High Space Utilization: Multi-story design maximizes land use efficiency.

Low Maintenance Costs: Steel structures are durable and require minimal maintenance.

1. Rational Structural Design

· Frame Systems: Utilize rigid or semi-rigid frame systems to ensure loads are evenly transferred through beams, columns, and joints.

· Bracing Systems: Install horizontal bracing (e.g., shear walls, cross-bracing) and vertical bracing to enhance the overall stiffness and stability of the structure.

· Load Distribution: Through calculations and optimization, ensure vertical loads (e.g., self-weight, equipment loads) and horizontal loads (e.g., wind, seismic loads) are evenly distributed across all components.

2. Node Design Optimization

· Rigid Joints: Use welding or high-strength bolts to ensure joints have sufficient stiffness and strength, avoiding localized stress concentration.

· Flexible Joints: In areas requiring deformation absorption (e.g., seismic zones), adopt flexible joint designs to allow controlled deformation while maintaining load uniformity.

· Joint Reinforcement: Reinforce critical joints (e.g., adding stiffeners or gusset plates) to prevent them from becoming weak points in the structure.

3. Material and Component Selection

· High-Strength Steel: Use high-strength steel to improve load-bearing capacity, reduce component size, and optimize load distribution.

· Uniform Cross-Sections: Employ components with uniform cross-sections (e.g., I-beams, box girders) to ensure even stress distribution and avoid localized stress.

· Prefabricated Components: Use factory-prefabricated components to ensure precise dimensions and quality, minimizing on-site installation errors.

4. Construction Quality Control

· Precise Installation: Strictly follow design drawings to ensure accurate positioning, alignment, and connection of components.

· Welding Quality: Conduct non-destructive testing (e.g., ultrasonic testing) on welds to ensure quality and prevent load imbalance caused by defects.

· Load Testing: Perform load tests after construction to verify structural performance and load uniformity.

5. Monitoring and Maintenance

· Real-Time Monitoring: Install sensors to monitor stress, deformation, and vibration, promptly identifying load imbalance issues.

· Regular Maintenance: Conduct periodic inspections and maintenance, repairing damaged or aging components to ensure long-term load uniformity.
