Introduction:
 
The Structural Load and Climate Coupling Test Chamber primarily simulates the effects of various environmental conditions on bridge structures. Full-parameter environmental simulation encompasses temperature and humidity, mechanical loading, salt spray, icing, snowfall, rain exposure, wind exposure, carbon dioxide, ultraviolet radiation, and saltwater immersion. By combining these parameters, the real-world environmental conditions across all regions of China can be comprehensively replicated.
 
Parameters:
 
1) Dimensions: 7m × 3m × 2.5m (L × W × H) (customizable)
2) Temperature: -40°C to 70°C, stability ≤ ±1°C, measurement accuracy ≤ ±0.5°C
3) Humidity: 30–98% RH, control accuracy ≤ ±5% RH
4) Salt spray: Saltwater concentration 5% , deposition rate 1–3 ml/80 cm²·h
5) Saltwater soaking: Saltwater concentration 3%–5%
6) Rainfall: 0.5–50 mm/h
7) Icing: Thickness 5 mm/h, vertically downward direction, adjustable inclination angle
8) Wind velocity: 0.5–10 m/s (Stability ±1 m/s)
9) CO₂: Concentration 0–20% V/V
10) UV Irradiation: Radiation intensity 63 W/m², UV fluorescent lamp with adjustable height
11) Mechanical loading: 500 kN actuator, static or dynamic loading
