Erection Analysis of a Large-Scale Radial Cable Net
Characteristics of radial cable nets are studied and the concept of erection analysis and design are proposed to simulate the whole erection process. Erection schemes are discussed based on behaivor of cable nets. Mechanism motion and elastic deformation are classified in the erection process. The proposed method is verified using a large-scale radial cable net. The case study indicates the proposed concept could be used to provide aids for erection analysis and simulation during the erection process. Index Term-- cable net, Construction simulation, tensile structure, prestress, erection analysis, and large deflection. I. INTRODUCTION Cable net roofs as one type of tensile structures, due to their lightweight and high flexural rigidity, are widely accepted in large-span structures since Matthew Nowicki designed the State Fair Arena at Raleigh in North Carolina in 1950, as shown in Fig. 1.
