Abstract:Mobile scaffold system was put forward according to the construction conditions of National Aquatic Center airinflated cushion membrane structure. The configurations of its lower supporting system and upper platform were introduced in detail. Integral stability was analyzed by modeling the whole structure and taking into account geometric nonlinear. The result of numerical analysis and the practices of project showed that carrying capacity of scaffolding system washigher and integral stability was better. The mobile scaffold system is suitable for the project which clearance is higher. It can reduce the cost of construction and speed up the progress.
