Retractable roof becomes popular in recent years because it can make the roof close, open or partly open to meet different purpose. The roof status can be changed according to climate condition outside. It can make people inside feel more comfortable and save energy sometimes. Mechanical system of retractable roof plays a very important role in system safety and reliability. With the experience of retractable roof of Kunshan indoor stadium, design of mechanical driving and supporting system is introduced. Calculation method for key parts and limitation for architecture structure are provided. This paper provides helpful reference for design of mechanical system on retractable roof.

This study presents a novel construction pre-supporting system for large underground space excavation with shallow depth, Steel Tube Slab system (STS), in which adjacent steel pipes are connected by a couple of flanges, bolts and concrete for flexural capacity and lateral stiffness of the whole structure. The STS method is employed for the first time for the construction of the ultra-shallow buried and large span subway station in China, during which ground settlement and structural deformation are monitored. A numerical model for the subway station is established with reliability verified by monitored data comparison from numerical results and investigation on the effect of large span underground excavation on surrounding soil surrounding soil and existing buildings in soft soils. Unlike traditional methods, the STS method can effectively control and reduce the ground settlement during construction, thereby rendering it ideally suited for application in soft soils.

Focused on the dynamical collapse of large-span spatial structure, this paper uses giant magnetostrictive material to design a kind of new GMM actuator, which could be used in active vibration control of large-span spatial structure. The genetic algorithm has been used to optimize the position of actuators in large-span spatial structure and the structure of fuzzy control system is introduced. A standard fuzzy logic controller is designed. Fuzzy control routine established by the matlab software is used to carry on the active control simulation analysis on the long-span spatial structures. The research shows that the GMM actuator has fine actuating effectiveness, and can improve the computational efficiency of optimization design at the same time. The genetic algorithm also achieves the overall optimization of the structure and the effect to the fuzzy control is obvious.
