RISCritical Success Factors for Transfer-Operate-Transfer Urban Water Supply Projects in China
Publisher: American Society of Civil Engineers
Abstract: Over the years, build-operate-transfer (BOT) has continuously attracted research interests. Many studies on BOT have been carried out. Variations of BOT such as build-own-operate-transfer and build-own-operate have also ...
Water Distribution System Optimization Considering Behind-the-Meter Solar Energy with a Hydraulic Power-Based Search-Space Reduction Method
Publisher: ASCE
Abstract: To meet increasing energy demands, reduce environmental impacts, and increase economic benefits, many water utilities have installed on-site renewable energy generation and storage facilities. These are commonly referred ...
Size Effect and Influence Factors of Asphalt Mixture Based on Particle Discrete Element
Publisher: ASCE
Abstract: To explore the size effect of asphalt mixture, asphalt mastic asphalt mixture was taken as the research object, and the uniaxial compressive strength was used as the evaluation index. The applicability of the three size ...
Degradation of GFRP Bars with Epoxy and Vinyl Ester Matrices in a Marine Concrete Environment: An Experimental Study and Theoretical Modeling
Publisher: ASCE
Abstract: This paper aimed to study the compatibility between E-glass of chemical resistance (ECR-glass) fibers and the polymer matrix and the influence of different matrix types on the durability performance of ECR-glass fiber–reinforced ...
Charpy Transverse Impact Failure Mechanisms of 3D MWK Composites at Room and Liquid Nitrogen Temperatures
Publisher: American Society of Civil Engineers
Abstract: The Charpy transverse impact experiments on the three-dimensional (3D) multiaxial warp knitted (MWK) composites with four fiber architectures are performed at room and liquid nitrogen temperatures (-196°C). Macrofracture ...
Defect Severity Assessment Model for Sewer Pipeline Based on Automated Pipe Calibration
Publisher: ASCE
Abstract: To address the low-efficiency issue of the manual assessment method for sewer pipe defects, we propose a defect severity assessment model based on automated pipe calibration (DSA-APC), which can provide automated and ...
