In this article, a novel idea of utilizing non-uniform rational B-spline (NURBS)-based material mesh independently defined with the analysis to represent distribution is introduced free vibration and buckling problems in-plane bi-directional functionally graded (IBFG) plates. Two power-law models symmetrical asymmetrical volume fraction are proposed as first experiment. By applying k-refinement scheme, C0-continuous condition at interfaces profiles can be easily achieved, while gradations...
As-built building information modeling (BIM) currently is regarded as a tool with the potential to manage buildings efficiently in operation and maintenance phases. However, as-built BIM labor-intensive process that requires considerable cost time existing buildings. Although active research on scan-to-BIM automation has addressed this issue, previous studies modeled only major objects such walls, floors, ceilings, consequently requiring other indoor spaces. In addition, there was limitation...
Conventional scan to building information modeling (BIM) automation mainly deals with geometry. However, one of its limitations is the time it takes and costs in generating material. Therefore, this study proposes an automated scan-to-BIM method considering both geometry material objects. It recognizes from a point cloud panorama images through deep learning–based semantic segmentation. The two extracted pieces data are merged, BIM objects automatically generated by using Dynamo. Here,...
The green loans program has continued to attract attention as an effective measure for promoting retrofit reduce energy consumption in old buildings. Various external factors negatively affect the decision-making process government and building owners. In particular, it is unclear how incentives penalties take effect what extent they can influence program. Therefore, this study identified of political factors, such loan support carbon taxation, on strategic choices results showed that (1)...
The significance of environmental management existing buildings in reducing the impact construction sector is increasingly emphasized. However, life-cycle assessment (LCA) to evaluate a building's burden requires considerable time and costs for collection interpretation data needed analysis. Therefore, this study proposed an integrated framework economic, environmental, human health impacts using scan-to-building information modeling (BIM) LCA buildings. To verify framework, case was...
Purpose: As the construction industry accounts for a significant portion of global carbon dioxide emissions, importance reducing emissions through remodeling existing buildings is being emphasized. This study proposes method to evaluate greenhouse gas each building material in process by integrating BIM and LCA, visualizing this model. Method: Using models, quantity cost are calculated, evaluated LCA. Then, these visualized model using Dynamo-based parametric algorithm. analyzed total five...
Surrogate modeling techniques are widely employed in solving constrained expensive black-box optimization problems. Therein, Kriging is among the most popular surrogates which trend function considered as a constant mean. However, it also encounters several challenges related to capturing overall with relatively limited number of evaluations well searching feasible points complex or discontinuous regions. To address this above issue, paper presents an improved surrogate blind (IBK) and...
The significance of fire inspection has been underscored to prevent building fires, which can lead property damage and loss life. While previous studies employed information modeling (BIM) evaluate safety performance, they primarily focused on a building's physical characteristics, overlooking environmental factors. To address this limitation, we propose framework BIM-based quantitative evaluation, incorporates both characteristics buildings enhance their performance. We conducted case study...
While the social sustainability of built environments is an essential aspect architectural design education, systemic experiments still lack empirical pedagogy. Therefore, factors are hardly reflected in students’ projects seamlessly. To overcome such limitations, this study investigates applicability and effectiveness human behavior simulation. ensure authentic design, were equipped with autonomous, rational anthropomorphic computer agents called virtual users (VUsers). This compared...
