RISSpatial-Sensitivity Analysis for Urban Color Planning: Study of Luoyang City, China
Publisher: American Society of Civil Engineers
Abstract: As they undergo rapid urbanization, many Chinese cities are lacking color coordination among their buildings. Although there has been substantial research on urban colors in the West, such studies are less developed in the ...
Kinematic and Geometric Analysis of a Pure-Rolling Epicyclic Train
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an innovative design of epicyclic (planetary) cam trains based on pure-rolling contact, intended to overcome the drawbacks of gear trains, such as Coulomb friction and backlash. ...
Urban Design Storm Hyetograph Analysis Based on a New Method Considering Spatiotemporal Variations
Publisher: ASCE
Abstract: Design storms guarantee uniformity regarding quality and operation standards of engineering projects and have been employed widely in urban drainage system design. Commonly used urban design storms, such as the Chicago ...
Evolution of the Overlying-Strata-Bearing Structure and the Permeability Distribution of the Broken Interlayer in Shallow Multiseam Mining
Publisher: ASCE
Abstract: Due to the particularity of the occurrence characteristics of shallow multiseam mining, underground mining space is vulnerable to obvious roof behaviors and serious gas anomalies, which are closely related to the destruction ...
Erratum for “Experimental and Simulation Studies on the Impact of Sluice Regulation on Water Quantity and Quality Processes” by Yongyong Zhang, Jun Xia, Quanxi Shao, and Xiang Zhang
Publisher: American Society of Civil Engineers
Experimental and Simulation Studies on the Impact of Sluice Regulation on Water Quantity and Quality Processes
Publisher: American Society of Civil Engineers
Abstract: Research on the impact of sluice regulation on water quantity and quality (WQQ) processes in regulated rivers is a fundamental requirement in basin management at present but remains a research puzzle at the basin scale ...
SPH Modeling of Wave Transformation over a Coral Reef with Seawall
Publisher: American Society of Civil Engineers
Abstract: Wave transformations over a coral reef with a steep front slope were comparatively studied using both laboratory tests and smoothed particle hydrodynamic (SPH) modeling. In the numerical model, nonreflective generation and ...
Global Seismic Damage Model of RC Structures Based on Structural Modal Properties
Publisher: American Society of Civil Engineers
Abstract: A macroscopic global seismic damage model is proposed for reinforced concrete structures by considering the dynamic modal contributions. Modal damage is defined using the concepts of dynamic modal stiffness and modal mass. ...
Fatigue Cracking Analysis of Asphalt Concrete Based on Coupled XFEM-Continuum Damage Mechanics Method
Publisher: ASCE
Abstract: Fatigue cracking is a major distress in asphalt concrete and has a significant influence on material performance. A coupled extended finite element method (XFEM)-continuum damage mechanics (CDM) model was developed in this ...
Greenhouse Gas Emissions Drive Global Dryland Expansion but Not Spatial Patterns of Change in Aridification
Publisher: American Meteorological Society
Abstract: Drylands play an essential role in Earth’s environment and human systems. Although dryland expansion has been widely investigated in previous studies, there is a lack of quantitative evidence supporting human-induced changes ...
