RISEffects of Physicochemical Properties of Nanofiltration Membranes on the Rejection of Small Organic DBP Precursors
Publisher: American Society of Civil Engineers
Abstract: In this study, two types of commercial nanofiltration (NF) membranes (NF70 and NF270) were chosen to remove four model disinfection by-product (DBP) precursors (resorcinol, phloroglucinol, 3-hydroxybenzoic acid, and tannic ...
Effects of Pounding and Skewness on Seismic Responses of Typical Multispan Highway Bridges Using the Fragility Function Method
Publisher: American Society of Civil Engineers
Abstract: This paper uses the fragility function method to study the effects of pounding and skewness on the seismic behaviors of typical multispan RC highway bridges. Three-dimensional numerical models are built for typical three-span ...
Research on the Mechanical Properties of a New “I†Type Double Decker Ball Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The new “I†type doubledecker ball bearing (NITDDBB) with two inner contact ball bearings is proposed to improve the speed and load capability of the original I type doubledecker ball bearing (OITDDBB). Based on the ...
Solute Transport in Heterogeneous Field
Publisher: American Society of Civil Engineers
Abstract: A laboratory study was conducted to study inert solute transport in a heterogeneous field. Twenty-one relatively undisturbed soil columns were sampled from a field plot, and chloride tracer tests were carried out in these ...
Simplified Drift Demand Prediction of Bridges under Liquefaction-Induced Lateral Spreading
Publisher: American Society of Civil Engineers
Abstract: This paper develops a simplified method to quantify the effects of liquefaction-induced lateral spreading on bridge responses, expressed as the response modification factor of the column drift ratio under seismic shaking. ...
Dynamic Deformation Control of Retaining Structures of a Deep Excavation
Publisher: American Society of Civil Engineers
Abstract: Many uncertain factors in the excavation process may lead to excessive deformations and internal forces of retaining structures; therefore, the design of deep excavations should be adjusted according to real-time monitoring ...

Establishment and Implementation of Source Water Implementation Plan for Water Treatment Plants in Taiwan
Publisher: American Society of Civil Engineers
Abstract: In accordance with the source water implementation plan rule (SWIPR) in Taiwan, water treatment plants (WTPs) with source water parameters exceeding the source water quality standards are required to submit a source water ...
Investigation of Formation Damage Induced During Drill-In Process of Ultradeep Fractured Tight Sandstone Gas Reservoirs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultradeep fractured tight sandstone gas reservoir is easy to suffer from severe formation damage during the drill-in process, yet few papers have been published on the corresponding formation damage mechanisms. This paper ...
Modeling and Simulation of Building Cooling System With Supercooling-Based Ice Energy Storage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: City’s electricity power grid is under heavy load during on-peak hours throughout summer cooling season. As the result, many utility companies implemented the time-of-use rate of electricity leading to high electricity ...
