This project adopts a typical portal rigid frame steel structure system with long-span and clear-span characteristics. The whole structure features reasonable force transmission, high overall rigidity, excellent wind and seismic resistance, and stable mechanical performance. The detailed force analysis is as follows:

 

2.1 Overall Force Transmission System

The building adopts a 6-meter longitudinal frame spacing and 25-meter transverse clear-span layout without intermediate supporting columns. The main load-bearing system is composed of variable-section H-shaped steel columns and beams, which bear all vertical static load, live load, horizontal wind load and seismic load. C-section purlins serve as the secondary stress-bearing system for walls and roofs, transferring surface loads uniformly to the main rigid frame. The bracing system forms a stable spatial integral structure with the main frame, ensuring balanced and layered force transmission without local stress concentration.

The variable-section design of main beams and columns optimizes section configuration according to actual bending moment and shear force distribution of the structure. The section size changes dynamically along the force direction, which effectively reduces self-weight and steel consumption on the premise of meeting bearing capacity requirements, realizing high-efficiency structural force bearing.

 

2.2 Wind Resistance Mechanical Performance Analysis

Designed for a wind speed of 120 km/h, the structure is optimized for strong wind loads applicable to tropical coastal areas. The rigid frame connection improves the lateral integral rigidity of the warehouse, effectively resisting horizontal wind pressure and reducing structural lateral displacement and wind-induced vibration. The complete bracing system enhances the overall torsional resistance of the building and avoids structural deformation or damage under sustained strong wind conditions.

The shot blasting derusting and epoxy zinc-rich primer anti-corrosion treatment eliminates structural performance attenuation caused by high humidity, salt spray and strong wind erosion in coastal environments, ensuring long-term stable wind resistance and structural safety.

 

 

2.3 Seismic Resistance Structural Performance Analysis

Grade 8 seismic fortification belongs to high-level seismic protection standard, adapting to high-seismic active zones. The steel structure has excellent ductility and energy dissipation capacity. Under seismic action, the rigid frame nodes can absorb seismic energy through micro elastic-plastic deformation, avoiding brittle failure and sudden collapse of the structure.

The matched steel consumption of main frame, purlins and bracing system forms a uniform rigidity distribution system, which effectively resists horizontal seismic shear force. The arrangement of a large number of foundation anchor bolts strengthens the connection rigidity between the superstructure and the foundation, preventing structural sliding, overturning and differential settlement under earthquake conditions, meeting high-standard seismic safety requirements.

 

2.4 Local Force Adaptability of Mezzanine Structure

The two-end independent mezzanines adopt reinforced connection structures. The local vertical load and shear force of the mezzanines are independently optimized without affecting the overall force balance of the 90-meter main warehouse structure. The local stiffening design ensures the stability and safety of the mezzanine area under daily use load and accidental dynamic load, realizing the integration of large-span storage space and local functional operation space.

 

2.5 Comprehensive Structural Mechanical Advantages

The whole structure features light self-weight, high strength, clear force transmission path, strong deformation resistance and high safety margin. The standardized component design supports factory prefabrication, modular integral packaging and container centralized shipment, with low on-site assembly difficulty and short construction cycle. The overall structure is highly adaptable to tropical coastal industrial park construction environments with complex meteorological and geological conditions.
