RISCase Study of Application of FRP Composites in Strengthening the Reinforced Concrete Headstock of a Bridge Structure
Publisher: American Society of Civil Engineers
Abstract: Worldwide interest is being generated in the use of fiber-reinforced polymer composites (FRP) in the rehabilitation of aged or damaged reinforced concrete structures. As a replacement for the traditional steel plates or ...
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 ...
Deterioration Rates of Building Component Groups Using Nominal Replacement Costs of Components
Publisher: ASCE
Abstract: Predictive modeling of deterioration is typically done based on visually inspected condition ratings of building components. This paper presents the concept of a cumulative lost value ratio (CLVR) for component groups to ...
Correlations between Mechanical Properties of Low-Calcium Fly Ash Geopolymer Concretes
Publisher: American Society of Civil Engineers
Markov Model—Based Building Deterioration Prediction and ISO Factor Analysis for Building Management
Publisher: American Society of Civil Engineers
Abstract: While the Markov chain was successfully used for predicting the average condition of a network of assets under one influencing factor, incorporating the effect of a number of factors into a Markov chain model requires a ...
Prediction of Life-Cycle Expenditure for Different Categories of Council Buildings
Publisher: American Society of Civil Engineers
Abstract: The prediction of the performance or service life of a building system and their components is a very complex task. Although many papers related to material and component durability have been published over the past two ...
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 ...
Alkali-Activated Slag Concrete with Recycled Aggregate: Long-Term Performance
Publisher: ASCE
Abstract: This paper evaluates the long-term mechanical properties (up to 1 year) of alkali-activated slag concrete produced with recycled coarse aggregate (AAS-RA) and natural coarse aggregate (AAS-NA). The AAS-RA achieved a ...
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 ...
