Structural Load and Climate Coupling Laboratory

Introduction: Primarily simulates the impact of various environmental conditions on bridge structures. The comprehensive parameter environmental simulation includes temperature and humidity, mechanical loading, salt spray, ice coating, snowfall, rain spray, wind blowing, carbon dioxide, UV radiation, and saline immersion. Through the combination of different parameters, it can essentially cover the real environmental conditions across various regions in China.

Parameters:

1) Dimensions: 7m×3m×2.5m (L×W×H) (Customizable)

2) Temperature: -40℃ to 70℃, stability ≤ ±1℃, measurement accuracy ≤ ±0.5℃

3) Humidity: 30 to 98%RH, control accuracy ≤ ±5%RH

4) Salt Spray: Saline concentration 5%, sedimentation rate 1-3ml/80cm².h

5) Saline Immersion: Saline concentration 3% to 5%

5) Rain Spray: 0.5 to 50mm/h

6) Ice Coating: Thickness 5mm/h, direction vertically downward, adjustable tilt direction

7) Wind Speed: 0.5 to 10m/s (stability ±1m/s)

8) CO2: Concentration 0 to 20% V/V

9) UV Radiation: Radiation intensity 63w/m², UV fluorescent lamps adjustable vertically

10) Mechanical Loading: 500kN actuator, static or dynamic loading

(All the above parameters can be custom-designed according to user requirements)
