Determining the cable installation location of soft retractable structures using 3D numerical data of the drone

Indoor gymnasiums and dome stadiums are mostly made of fixed hard structures, which leads to economic loss due to the continuous operation of ventilation and lighting equipment. When the roof of a large space is installed by retractable method, it secures comfortable environment by natural light during the daytime and reduces ventilation costs. The retractable spaces can be constructed in hard and soft structures. In the case of soft structures, cables and membrane are the primary components. In order to install the cables, it is necessary to determine the location of the central part where each cable meets. However, the existing approach depending on only some workers shows a limited ability in investigating the appropriateness of the installed cables. Therefore, this study aims to propose a method to determine the installation location of the soft retractable structure cables based on the numerical data derived from drones. Factors that can inspect the construction quality of cables and membrane materials in the construction stage and construction completion stage were identified. Based on the construction guidelines of the Ministry of Land, Infrastructure and Transport of Korea (MOLIT), standard specifications, and relevant similar cases, the applicability of the method using the numerical data of the drone was investigated.
