Abstract: Water distribution systems (WDSs) are crucial urban infrastructures playing major roles in maintaining the social and economic functions of modern cities. Understanding the operation condition contributes to daily maintenance, ...

Abstract: The effects of different types of earthen landfill covers and vapor on landfill gas emissions are not well understood. In this study, an existing theoretical model of water and multicomponent gas (methane, carbon dioxide, ...

Abstract: The feasibility of reducing the cost of solar water heating systems by using polymer heat exchangers is illustrated by comparing thermal performance and cost of heat exchangers made of nylon, ...

Abstract: The vibration serviceability of an as-built long-span concrete floor was assessed using field measurements taken during the structure’s daily use and under controlled human activities including a group of people walking ...

Abstract: Modal identification with output-only measurements plays a key role in vibration-based damage detection, model updating, and structural health monitoring in civil engineering. This paper addresses ...

Abstract: The use of concrete-filled hollow structural steel (HSS) columns has become widespread in the past few decades. However, these members are subject to static long-term behaviors under sustained loading, a common phenomenon ...

Abstract: Although energy dissipation devices (EDDs) have been used as a viable strategy of seismic protection of buildings for many years, current design codes do not provide guidelines for optimizing EDD configurations that may ...

Abstract: This study develops a method to depress the evolution of ammonia by blending aluminum dross samples with various doses of an aqueous ferrous chloride solution. Results show that ammonia evolutions can be reduced from

Abstract: A description of yield surfaces in the axial-torsional-hoop stress space, which is able to capture the yield surface expansion/contraction, translation, rotation, affine deformation, and distortion, is constructed under a ...

Abstract: This paper proposes a semianalytical solution to analyze the long-term settlement of a single pile embedded in fractional derivative viscoelastic soils under time-dependent loading. In this paper, a three-dimensional (3D) ...
