Abstract: The main entrance gate of the 10 th China Flower Expo is made of a vein-shaped steel structure attached with PVDF tensioned membrane. It is 19.21 meters high, 100 meters long and 40 meters wide so that the attached PVDF membrane is nearly 4 800 m2. In order to precisely cut and install the 3 D heterogeneous membrane materials, a new method is developed and introduced in this paper. The attached membrane is divided into 10 symmetric membrane units and the installation sequence of all units is designed. Then, 3 D measured data of the steel truss are imported into BK cutting machine to digitally process the membrane materials. After that, the membrane units are efficiently installed and elastically fastened through the erection of cobwebbed operation platform.
