Effect of Runtime on the Deterioration of HVAC Components in Building Services
Publisher: ASCE
Abstract: Heating, ventilation, and air conditioning components are among the significant component groups in building services. Around 50% of a buildings’ energy consumption is related to HVAC systems. Published research has indicated ...
Network Deterioration Prediction for Reinforced Concrete Pipe and Box Culverts Using Markov Model: Case Study
Publisher: ASCE
Abstract: Reinforced concrete (RC) pipe and box culverts are widely used as an alternative to bridge structures in road transport networks around the world. The deterioration of the RC culverts is a complex problem caused by combined ...
Stochastic Prediction of Road Network Degradation Based on Field Monitoring Data
Publisher: ASCE
Abstract: Asset management of pavement network requires understanding of pavement deterioration rate for cost-effective maintenance and adequate budget allocation. The pavement industry has recognized the challenge of uncertainty ...
Extending Service Life of Stormwater Drainage Pipes with Proactive Maintenance Tools
Publisher: American Society of Civil Engineers
Abstract: Aging infrastructure is a significant concern to many system operators who might struggle to operate, maintain, and improve systems and infrastructure assets due to spatially buried assets over a large area, uncertainty ...
Estimating Cost of Bridge Closure for Bridge Network Rehabilitation Priorities
Publisher: American Society of Civil Engineers
Abstract: Bridge network maintenance and rehabilitation activities are crucial to prevent bridge failure from human-made and natural hazards such as deterioration, overload, collision, fire, flooding, and earthquake. Under a limited ...
Markov Chain–Based Inspection and Maintenance Model for Stormwater Pipes
Publisher: ASCE
Abstract: Inspection and maintenance (M&R) of a buried network of stormwater drainage pipes is a challenging task for asset engineers due to a large number of pipes and restricted access. A Markov-based inspection model with a ...
Using Snapshot Data of Deficiency and Generic Deterioration to Predict the Degradation of Building Elements
Publisher: ASCE
Abstract: The typical approach to modeling building degradation is based on consecutive visual inspections using generic deterioration ratings to characterize the conditions of elements. Our research used snapshot data to capture a ...
Enhancement of the Catalytic Ozonation Process by Using TiO<sub>2</sub>/ZrO<sub>2</sub> Nanoparticles
Publisher: American Society of Civil Engineers
Abstract: In this study, we employed synthesized titanium oxide/zirconium oxide (TiO2/ZrO2) nanoparticles as activated catalysts to enhance the ozonation process during hydroxyl radical (OH°) generation using atrazine (ATZ) as a ...
