RISChallenges in the Application of Stochastic Modal Identification Methods to a Cable-Stayed Bridge
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analysis of the data collected in the ambient vibration test of the International Guadiana cable-stayed Bridge, which links Portugal and Spain, based on different output-only identification techniques: ...
Identification of Residential Energy Consumption Behaviors
Publisher: American Society of Civil Engineers
Abstract: Climate change has raised consciousness of the need to use cleaner energy instead of fossil fuels. Meanwhile, a change of consciousness regarding resource use has to be achieved, which can be triggered by energy consumption ...
Modal Analysis for the Rehabilitation Assessment of the Luiz I Bridge
Publisher: American Society of Civil Engineers
Abstract: Dynamic testing in the condition assessment of existing bridges to support their rehabilitation and strengthening designs is becoming a common procedure, yet additional dynamic testing after rehabilitation is rare. ...
Vertical Crowd–Structure Interaction Model to Analyze the Change of the Modal Properties of a Footbridge
Publisher: American Society of Civil Engineers
Abstract: In this paper, a biomechanical crowd–structure interaction model is proposed and further implemented to adequately estimate the energy exchange between pedestrians and a footbridge. The proposed model focuses on the ...

Optimization of Phenol Removal from Biorefinery Effluent Using Horseradish Peroxidase
Publisher: American Society of Civil Engineers
Abstract: Biorefinery is a facility comprising industrial processes for the production of fuel and chemicals from biomass. Because there is a growing number of biorefineries worldwide, the related environmental aspects have to be ...
Combined Experimental-Operational Modal Testing of Footbridges
Publisher: American Society of Civil Engineers
Abstract: In combined vibration testing, an artificial, measured force is used in operational conditions. This requires the identification of a system model that takes both the measured and the operational excitation into account. ...
Planning and Design of Urban Flood Control Measures: Assessing Effects Combination
Publisher: American Society of Civil Engineers
Abstract: Different approaches related with urban flood problems treatment are evolving and there is a large set of possible engineering measures that can be applied. Lately, the traditional approach, focusing on improving channel ...
Hybrid Polymer Gear Concepts to Improve Thermal Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A drawback of polymer materials is their low thermal conductivity which affects the operating temperature of polymer gears. The mechanical properties of a polymer gear are critically dependent on the maximum operating ...
The Duke University Helicopter Observation Platform
Publisher: American Meteorological Society
Abstract: To establish a helicopter observation platform (HOP), Duke University has purchased a Bell 206 ?Jet Ranger? helicopter, which has been equipped with a three-dimensional, high-frequency positioning and attitude-recording ...
