Developments In Construction Workers’ Compensation Insurance With The Use Of Biometrics, Kobe Tooch Jun 2023

Developments In Construction Workers’ Compensation Insurance With The Use Of Biometrics, Kobe Tooch

Construction Management

Construction insurance, especially that of workers’ compensation, is vital for the protection of general contractors, but it comes at a high cost and limits their control over contract terms. Biometric devices, such as heart rate monitors and motion capture, have the potential to revolutionize the industry by reducing construction insurance premiums. Heart rate monitors can provide real-time data on workers' physical activity and health, while motion capture analyzes movements to identify unsafe movement patterns performed by workers. By monitoring workers' biometrics, construction companies can ensure their safety, prevent hazards, and implement targeted training programs. This personalized data can lead to …

Assessing The Effectiveness Of Noise Ordinances On Residential Construction: A Case Study In San Luis Obispo, Duncan Catley Jun 2023

Assessing The Effectiveness Of Noise Ordinances On Residential Construction: A Case Study In San Luis Obispo, Duncan Catley

Construction Management

Construction activities inherently generate substantial noise. As a result, construction becomes a notable source of ambient sound that permeates populated areas daily. This sound, especially at extreme volumes, can be the source of significant public annoyance and anger. Studies have shown that prolonged noise exposure can lead to hypertension, distraction, and even cognitive impairment in children. For these reasons, local governments will set noise ordinances to limit when and at what volume construction sounds can be made. The purpose of this study was to determine the effectiveness of these noise ordinances set by the city of San Luis Obispo. The …

Ecological Validity Of Immersive Virtual Environment Experiments On Human Thermal State And Behavioral Intentions: Experimental Protocol Factors, Girish Rentala May 2023

Ecological Validity Of Immersive Virtual Environment Experiments On Human Thermal State And Behavioral Intentions: Experimental Protocol Factors, Girish Rentala

LSU Doctoral Dissertations

Using immersive virtual environment (IVE) based experiments to investigate human thermal states and thermal adaptive behaviors during the building design phase could help identify potential comfort issues and enable designers to optimize building performance cost-effectively before the actual building construction. However, to effectively utilize IVEs to study thermal states/adaptive behaviors, it is crucial to ensure the ecological validity of IVE experiment protocols. This entails accurately representing in-situ (real) environments within IVEs and establishing comparability and generalizability of data collected under different thermal stimuli between IVE and in-situ environments. Existing thermal stimuli based IVE studies have not effectively evaluated the ecological …

Using Bim To Increase The Efficiency Of Energy-Driven Retrofitting Projects, Anne Grego, Shannon Chance, Barry Mcauley May 2023

Using Bim To Increase The Efficiency Of Energy-Driven Retrofitting Projects, Anne Grego, Shannon Chance, Barry Mcauley

Conference Papers

The building sector is responsible for nearly 40% of global energy consumption. Many existing buildings have poor thermal insulation and low energy performance, hindering sustainability goals. Energy-driven building retrofitting could address this issue and implementing Building Information Modelling (BIM) in retrofitting can reduce process time, costs, and waste associated with such undertakings. Yet, there is a lack of research and insufficient guidance for implementing BIM in energy-driven retrofitting. A BIM framework is presented to enhance decision-making processes during retrofitting. The aims of this study were to (1) identify BIM technologies and methodologies that could address existing barriers and improve efficiency …

Application Research And Prospect Of Passive Battered Pile, Zhou Dequan, Wang Chuangye, Zhou Yi, Zhao Yadang May 2023

Application Research And Prospect Of Passive Battered Pile, Zhou Dequan, Wang Chuangye, Zhou Yi, Zhao Yadang

Journal of China & Foreign Highway

Battered piles oriented in specific directions demonstrate superior horizontal load-bearing capacity compared to vertical piles. However, the working mechanism of battered piles remains inadequately understood, and corresponding design standards are yet to be established. These limitations hinder the effective utilization and application of the horizontal load-bearing and stability potential of battered piles. This paper comprehensively analyzes the soil-pile interaction mechanisms, horizontal displacement, and load-bearing behavior of passive battered piles and their composite systems under lateral unloading and lateral loading conditions, using model tests, numerical simulations, and theoretical analysis. In addition, it proposes future research directions aimed at advancing the study …

Study On Applicability Of Flexible Gabion Revetment In Soft Soil Subgrade In Lake District, Su Weiwei, Lei Mingxuan, Liu Guotian, Zhang Liujun, Liu Junyong May 2023

Study On Applicability Of Flexible Gabion Revetment In Soft Soil Subgrade In Lake District, Su Weiwei, Lei Mingxuan, Liu Guotian, Zhang Liujun, Liu Junyong

Journal of China & Foreign Highway

Based on FLAC3D finite difference software, this paper conducts numerical simulations of both flexible gabion revetment structures and rigid revetment structures to compare their deformation and stress characteristics. The results indicate that the flexible gabion revetment structure demonstrates excellent applicability for soft soil subgrades in lake districts. Compared with rigid revetment structures, the gabion revetment structure improves overturning stability through coordinated deformation within the foundation. It significantly reduces the basal stress, thus lowering the bearing capacity requirements for the foundation, and ensures a more uniform stress distribution at the base, minimizing differential settlement and enhancing foundation stability. Moreover, the gabion …

Research And Application Of Dynamic Compaction Treatment Method For Highway Subgrade In Karst Development Area, Liu Xiaoming, Wang Yigang, Zhao Minghua May 2023

Research And Application Of Dynamic Compaction Treatment Method For Highway Subgrade In Karst Development Area, Liu Xiaoming, Wang Yigang, Zhao Minghua

Journal of China & Foreign Highway

This paper utilizes discrete-continuum coupled numerical simulation to investigate the failure modes of karst cave roofs with varying spans under specific compaction energy levels. The relationship between the span of the cave roof and the compaction energy required to cause roof collapse is established, providing an estimation method for the maximum unsupported span of cave roofs within the subgrade area. Based on this, the stability of karst cave foundations under the influence of subgrade loads can be evaluated. Depending on the results, a double-layer reinforced continuous concrete slab can be installed in the pavement base to enhance stability and mitigate …
