Beijing Space Frame Consulting Co. and Shanghai Tent Membrane Structures Co. , Ltd were involved with the engineering of the indoor exhibition building named "Special Hall". Figure 1 shows the sketch of the winning project, designed by Shanghai Sunyat Architecture Design Co., Ltd. The project is 82mx50m, 22m high and has a surfaced area of about 6000m2.The winning project was further developed by using a monolayer steel grid shell. This kind of structures look slim and are eye-catching. A light single layer made of ETFE was used to complete the construction.Detailing the design is a challenge. To achieve an optimal result for this project Shanghai Tent Membrane Structures Co., Ltd and Beijing Space Frame Consulting Co. developed a new clamping system to connect the ETFE membrane to the steel grid shell.
