RISAdaptive Greenhouse with Thermochromic Material: Performance Evaluation in Cold Regions
Publisher: ASCE
Abstract: The intensive energy requirement is a major challenge for greenhouse producers, especially those located in cold regions. An adaptive greenhouse with thermochromic (TC) material has the potential to intelligently regulate ...
Multiscale Chemico-Thermo-Hydro-Mechanical Modeling of Early-Stage Hydration and Shrinkage of Cement Compounds
Publisher: American Society of Civil Engineers
Abstract: The early-stage cement hydration is critical to the strength and durability of cement-based materials. Due to the complex processes involved, holistic multiphysics and multiscale simulation is challenging. This paper ...
Soil Water Content and Dry Density by Time Domain Reflectometry
Publisher: American Society of Civil Engineers
Abstract: Soil water content and dry density are two important properties for compaction quality control. This paper presents a new method for determining soil water content and dry density using a single time domain reflectometry ...
Characterization of the Optical and Mechanical Properties of Innovative Multifunctional Thermochromic Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Conventional asphalt binder material strongly absorbs solar energy due to its black color. The consequent high surface temperature of asphalt pavement during the summer accelerates rutting, impairs long-term durability, ...
Investigation of Internal Frost Damage in Concrete with Thermodynamic Analysis, Microdamage Modeling, and Time-Domain Reflectometry Sensor Measurements
Publisher: American Society of Civil Engineers
Abstract: This study investigates the internal-frost damage due to ice-crystallization pressure in the concrete pore system. The methodology integrates thermodynamic analysis and a microdamage model as well as a unique time-domain ...
Reliability Analysis of Water Distribution Systems Using Physical Probabilistic Pipe Failure Method
Publisher: American Society of Civil Engineers
Abstract: Water distribution systems (WDSs) are among the most essential infrastructure systems for the sustenance of societies. Therefore, their continued reliability is of utmost importance. However, the reliability of WDSs decreases ...
Asset Management Decision Support Model for Water Distribution Systems: Impact of Water Pipe Failure on Road and Water Networks
Publisher: ASCE
Abstract: Failure of a buried water pipeline can have an adverse effect on neighboring infrastructure, especially road networks. The impact of the failure of water pipelines on road networks and water distribution systems (WDSs) ...
Framework for Seismic Damage and Renewal Cost Analysis of Buried Water Pipelines
Publisher: ASCE
Abstract: Buried water pipelines suffer extensive damages when subjected to earthquake loading. Probable seismic damage of buried pipelines is typically estimated based on empirical analyses, where the effects of corrosion deterioration ...
Time Domain Reflectometry Surface Reflections for Dielectric Constant in Highly Conductive Soils
Publisher: American Society of Civil Engineers
Abstract: This paper presents a model-based approach to determine dielectric constants from time domain reflectometry (TDR) measurement in highly conductive soils. It makes use of information contained in the TDR signal from the ...
Seismic Functionality and Resilience Analysis of Water Distribution Systems
Publisher: ASCE
Abstract: Buried water pipelines are subjected to corrosion deterioration and are vulnerable to extreme events (e.g., earthquakes). Corroded metallic buried pipelines have experienced severe damage during past earthquakes ...
