RISAnalysis of the Effect of Porosity in Concrete under Compression Based on DIP Technology
Publisher: ASCE
Abstract: On a mesoscopic scale, concrete is considered to be a heterogeneous composite material which is composed mainly of cement mortar, aggregate, an interface transition zone (ITZ), and pores. The mesoscopic model of concrete ...
Prediction of Elastic Properties of Cementitious Materials Based on Multiphase and Multiscale Micromechanics Theory
Publisher: American Society of Civil Engineers
Abstract: Prediction of the elastic properties of cementitious materials has been the aim of many researchers. This study developed a new multiscale and multiphase model based on the Mori-Tanaka method for predicting effective elastic ...
Effect of Alkali Content on the High-Temperature Behavior of Alkali-Activated Slag Paste Containing MSWI Bottom Ash
Publisher: ASCE
Abstract: The accumulation of municipal solid waste incineration bottom ash (MSWI-BA) not only occupies land, but also leads to severe environmental pollution. In order to improve the utilization of MSWI-BA and reduce carbon emissions, ...
Configuring Governance Mechanisms to Improve the Engineering Consulting Project Performance
Publisher: American Society of Civil Engineers
Abstract: Extensive research has demonstrated the significance of project governance in enhancing project performance. However, previous studies have not dealt with the problem of governance mechanism design for engineering consulting ...

Local Scouring around Twin Bridge Piers in Open-Channel Flows
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were carried out to investigate local scouring around twin cylindrical piers in open-channel flows. The experimental results of clear-water scouring around the twin piers show that the scour hole ...
Mining Urban Sustainability: Vehicle Emission Changes on Traffic Corridor by One-Way Traffic Conversion
Publisher: ASCE
Abstract: A one-way traffic strategy is widely used in densely populated urban areas to improve traffic efficiency, but its environmental impacts remain largely unclear. This study investigated the effects of a one-way traffic ...
Experimental and Numerical Evaluation of the Effect of Rail on the Behavior of Girder Bridges
Publisher: ASCE
Abstract: This paper experimentally and numerically evaluates the participation of bridge rail in carrying live load through (1) performing field testing on steel and prestressed concrete girder bridges; (2) developing validated ...
Measuring Behavior of Long-Span Bridges during Erection: Case Study of the Governor Mario M. Cuomo Bridge
Publisher: ASCE
Abstract: The design of long-span cable-stayed bridges is governed by dead and erection loads, as well as wind loading. Despite the importance of dead and erection loads, their impact on the behavior of built structures is unknown, ...
Tensile Creep of Alkali-Activated Slag–Stainless Steel Slag Mortar: In-Depth Analysis of Effects and Mechanisms
Publisher: American Society of Civil Engineers
Abstract: Despite the excellent mechanical and environmental properties of alkali-activated materials, the susceptibility to early cracking significantly limits their widespread application in engineering. Tensile creep plays a key ...
