    Laboratories

    As an important part of “the National Key Laboratories for Building Safety and Environment,” CABR Tech has built up laboratories of shaking table, wind tunnel, innovative building materials, large-scale structures and green buildings, which are equipped with all necessary facilities and advanced equipments and can accomplish various experimental tasks of scientific research and consultation。

    Up to now, the shaking table laboratory is the largest in scale ( 6m×6m ) and standard load ( 60t ) and the most advanced in technology in China. Its technical index and control accuracy is among the top levels in international markets, and can carry out various earthquake shaking table experiments of complicated structures and shaking table experiments of various equipments and products.

    The wind tunnel laboratory ( construction area of 4665m² ) has a boundary layer wind tunnel with down-blowing double-spectrum, which is the largest in construction scale in China. The total length of the wind tunnel is 96.5 meters. Its high speed spectrum is 4m×3m×22m( width×height×length ) with the highest wind speed of 30m/s, and its low speed spectrum is 6m×3.5m×21m with the highest wind speed of 18m/s. With such advanced testing equipments as synchronous electronic scanning valve, multiple laser vibration meter and high-frequency scale, the laboratory can carry out research and consultation work on anti-wind and wind environment experiment, CFD numerical simulation, and wind vibration analysis.
