RISQuantifying the Effect of Mental Stress on Physical Stress for Construction Tasks
Publisher: ASCE
Abstract: Because of labor-intensive and physically demanding tasks, construction workers are known to be at a higher risk of developing physical fatigue. Recent studies have shown that construction workers are also often exposed ...
A Framework for Assessing the Impacts of COVID-19 on the Construction Industries in Developing Countries
Publisher: American Society of Civil Engineers
Abstract: The COVID-19 pandemic has struck the construction industry gravely. Accordingly, numerous studies reported the impact of COVID-19 on various aspects of the construction industry and projects. However, there exists no ...
Identification and Classification of Physical Fatigue in Construction Workers Using Linear and Nonlinear Heart Rate Variability Measurements
Publisher: ASCE
Abstract: Several studies have analyzed heart rate variability (HRV) using nonlinear methods, such as approximate entropy, the largest Lyapunov exponent, and correlation dimension in patients with cardiovascular disorders. However, ...
Online Assessment of Spontaneous Mental Fatigue in Construction Workers Considering Data Quality: Improved Online Sequential Extreme Learning Machine
Publisher: American Society of Civil Engineers
Abstract: Biological data-based methods for monitoring workers’ mental fatigue have become widely adopted in recent years. However, few have concentrated on the online monitoring and assessment of mental fatigue considering the ...
Monitoring Mental Fatigue of Construction Equipment Operators: A Smart Cushion–Based Method with Deep Learning Algorithms
Publisher: American Society of Civil Engineers
Abstract: Construction equipment operators (CEOs), who are required to work in seated positions for prolonged periods, often develop excessive mental fatigue, causing human error-related accidents, lower productivity, and psychological ...
Identification of Biomechanical Risk Factors for the Development of Lower-Back Disorders during Manual Rebar Tying
Publisher: American Society of Civil Engineers
Abstract: High prevalence of musculoskeletal disorders among construction workers pose challenges to the productivity and occupational health of the construction industry. To mitigate the risk of musculoskeletal disorders, construction ...
Low-Cost Ergonomic Intervention for Mitigating Physical and Subjective Discomfort during Manual Rebar Tying
Publisher: American Society of Civil Engineers
Abstract: The construction industry around the globe is facing a massive predicament of work-related musculoskeletal disorders (MSDs), largely attributed to the excessive physical exertion at worksites. Whereas ergonomic interventions ...
Construction Activity Recognition and Ergonomic Risk Assessment Using a Wearable Insole Pressure System
Publisher: ASCE
Abstract: Overexertion-related construction activities are identified as a leading cause of work-related musculoskeletal disorders (WMSDs) among construction workers. However, few studies have focused on the automated recognition ...
Automatic Biomechanical Workload Estimation for Construction Workers by Computer Vision and Smart Insoles
Publisher: American Society of Civil Engineers
Abstract: Construction workers are commonly subject to ergonomic risks due to awkward working postures or lifting/carrying heavy objects. Accordingly, accurate ergonomic assessment is needed to help improve efficiency and reduce ...
