Abstract

In the construction industry, 3D models are often used to share information among stakeholders. It is expected that the 3D model can be used for numerical analysis to perform detailed and advanced simulations. However, the models that can be constructed with commercially available 3D modeling software cannot be used for numerical analysis or can only be used with specific analysis tools. In addition, because commercial products are sold in packaged form, the use of the models is extremely limited. In 2021, Takeyama et al. developed a method for constructing a Grid Ground Model, which is a general purpose mediation model with general ground information, including boring data and soil test results. By building a common data structure once, flexible data manipulation can be performed. Based on this technology, this study developed a model building function that can be used for more advanced applications, including analysis using finite element analysis (FEA), by providing a high level of generality in the use of internal parameters and the geometry processing process. Using the developed technology, a detailed numerical analysis model was constructed through simple operations. This technology is useful for disaster damage estimation and advanced  design or maintenance of construction works. In addition, the models can be highly integrated with a wide variety of software, contributing to a significant reduction in the number of man-hours required for work and to the advancement of the use of 3D models in the future.
