Semiautomatic Structural BIM-Model Generation Methodology Using CAD Construction Drawings
(ASCE, 2020)Limited to the current building information model (BIM) development stage, many engineers are still using CAD 2D drawings for top-down design, and then using drawings to generate BIM models for BIM-related applications. ... -
Self-Supervised Structure Learning for Crack Detection Based on Cycle-Consistent Generative Adversarial Networks
(ASCE, 2020)Deep learning is a state-of-the-art approach to pixel-level crack detection. However, it relies on a large number of source–target image pairs for the training, which is very expensive. This paper proposes a self-supervised ... -
Feasible Prestress Modes for Cable-Strut Structures with Multiple Self-Stress States Using Particle Swarm Optimization
(ASCE, 2020)A prestressed cable-strut structure is usually regarded as a mechanism before being prestressed. Under the action of initial prestresses, the internal infinitesimal mechanisms can be rigidified, resulting in achieving the ... -
Detecting Leaks in Water Distribution Pipes Using a Deep Autoencoder and Hydroacoustic Spectrograms
(ASCE, 2020)Small leaks in buried water distribution pipelines typically remain undetected indefinitely because the impact small leaks have on the overall system pressure is imperceptible. This difficulty is caused by a combination ... -
IFC-Based BIM-to-BEM Model Transformation
(ASCE, 2020)Building information modeling (BIM) can facilitate evaluation of the energy performance of a building from the early stages of a project. However, due to differences in how information is represented in BIM and building ... -
Wearable Biosensor and Collective Sensing–Based Approach for Detecting Older Adults’ Environmental Barriers
(ASCE, 2020)In this rapidly aging society, the mobility of older adults is critical for the prosperity and well-being of communities. Despite such importance, various types of environmental barriers (e.g., steep slopes and uneven ... -
Automatic Detection of Geometric Errors in Space Boundaries of IFC-BIM Models Using Monte Carlo Ray Tracing Approach
(ASCE, 2020)In Industry Foundation Classes (IFC) building information modeling (BIM), the objectified concept of a space boundary (SB) provides a means to define building space geometries with surface entities. Such building-geometry ... -
Bilevel Decision-Support Model for Bus-Route Optimization and Accessibility Improvement for Seniors
(ASCE, 2020)Bus route networks play a pivotal role in public transit system planning, which, in turn, influences the geographical distribution and service coverage of bus transit. Although some advanced approaches have been applied ... -
Solving Resource-Constrained Project Scheduling Problem via Genetic Algorithm
(ASCE, 2020)The resource-constrained project scheduling problem (RCPSP) is an important and challenging problem in the field of construction management. This paper presents a genetic algorithm (GA) for the RCPSP. The proposed algorithm ... -
Robust Image-Based Surface Crack Detection Using Range Data
(ASCE, 2020)Image-based automated crack detection techniques have been developed and applied extensively during the past decade. However, issues existing in this type of methodology have not yet been fully addressed. Early studies ... -
Performance Studies of 10 Metaheuristic Techniques in Determination of Damages for Large-Scale Spatial Trusses from Changes in Vibration Responses
(ASCE, 2020)The determination of the location and severity of damage is a crucial task in the damage assessment of structures. In this study, 10 population-based metaheuristic techniques are applied to identify the location and severity ... -
Dynamic, Data-Driven Decision-Support Approach for Construction Equipment Acquisition and Disposal
(ASCE, 2020)Successful acquisition and disposal of construction equipment—a capital-intensive business process—requires both experience and expertise, particularly when assessing fair market values of equipment. Although advanced ... -
Illumination Compensation Model with <i>k</i>-Means Algorithm for Detection of Pavement Surface Cracks with Shadow
(ASCE, 2020)A small amount of research has been conducted in dealing with pavement shadow–affected cracks detection. Hence, this research aims to develop the illumination compensation model (ICM) and k-means clustering algorithm–based ... -
EvacuSafe: Building Evacuation Strategy Selection Using Route Risk Index
