Based on the analysis of the roof cable net system, the study formulated the overall sequence of membrane installation, and defined the construction method of membrane lifting and unfolding. Focusing on membrane fixing techniques with the tension rings, compression rings, and horizontal cable nodes, it also optimized membrane connection methods with arch and horizontal cable, and provided waterproof construction methods. According to the findings, the construction of stadium roof membranes should follow a logical sequence. The membranes’ fixing, connection and waterproof construction will have an important impact on the final quality.展开更多

First, a precise simulation of the surface-mounted cube was conducted. Validation testing based on the obtained data confirmed the predictive accuracy of Airflow Analyst. Second, New National Stadium Japan (Tokyo Olympic Stadium) was accurately reproduced in a computer, capturing the latest detailed urban area data for the base. For the target of the constructed 3D models, simulations with a large number of grid points/cells (CFD) were conducted. These simulations reproduced the complex turbulent flow fields both inside and outside the stadium. The experiment successfully reproduced the CFD simulation using a large number of grid points/cells, where the conditions of the wind flow ventilation from the sky were similar to those of the intended stadium design.展开更多
