For research on the aerodynamic characteristics of structures undergoing the acting of the sudden-change flow, the wind tunnel experiment for simulating the sudden-change airflow was introduced in this paper. Firstly, a profile of downburst gust was simulated using an active control wind tunnel. Secondly, the approach of change-step change airflow was(More)
With the development of technology, the more sensor and actuator are used on the building structure control, the more fault probability will become. This study introduces hierarchical decentralized fault tolerate controller design methods, which are constructed for sensor and actuator failures, based on Lyapunov approach. And it constructs cantilever active(More)
Aimed at the practical requirement of tubular joint welds inspection of offshore platform structures, the ultrasonic phased array inspection algorithm for offshore platform structures is proposed in this paper, and the ultrasonic phased array inspection system for offshore platform structures is developed. The experiment of tubular joint model is performed(More)
