RISReview of State-Of-The-Art: Drag Forces on Submarine Pipelines and Piles Caused by Landslide or Debris Flow Impact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Submarine landslides and debris flows are among the most destructive geohazards, economically and environmentally, for installations on the seafloor. Estimating the drag forces caused by these ...
Progressive Collapse Analysis of Steel Moment Frames: An Energy-Based Method and Explicit Expressions for Capacity Curves
Publisher: American Society of Civil Engineers
Abstract: This paper presents a simplified model to evaluate progressive collapse response of steel beam–column substructures in a midspan column removal scenario. The model accounts for the influence of the span:depth ratio of the ...
Comparison of Column Removal Methods in Progressive Collapse Analysis of Reinforced Concrete Moment-Resisting Frames
Publisher: American Society of Civil Engineers
Abstract: A building experiences progressive collapse when a primary structural element fails, resulting in the failure of adjoining structural elements, which in turn causes further structural failure. The final failure contains ...
Stochastic Optimization of Reservoir Operation by Applying Hedging Rules
Publisher: ASCE
Abstract: The high percentage of reliability of water resources systems has always been considered as a positive advantage by users. However, in arid and semiarid areas in which the flow rate of the reservoir is highly variable, it ...
Data-Driven Stochastic Approach for Assessing Future Risk of Wave Overtopping in Coastal Defense Structures
Publisher: American Society of Civil Engineers
Abstract: Rising sea levels due to climate change pose a significant threat to coastal regions, especially through wave overtopping, which can lead to hazardous flooding for coastal communities and emphasize the urgent need for ...
An Improved Closed Loop Heat Extraction Method From Geothermal Resources
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Disposal of produced water and induced earthquakes are two major issues that have endangered development of the geothermal energy as a renewable source of energy. To avoid these problems, circulation of a lowboiling working ...
Face Stability Evaluation of a TBM-Driven Tunnel in Heterogeneous Soil Using a Probabilistic Approach
Publisher: American Society of Civil Engineers
Abstract: The stability condition of the tunnel face is of great importance in both conventional and modern [tunnel-boring machine (TBM)] methods of construction. Inadequate and excessive amounts of support pressure toward the face ...
On Prediction of Thermal-Hydraulic Characteristics of Square-Sectioned Ribbed Cooling Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of an investigation on prediction of local and mean thermal-hydraulic characteristics in rib-roughened ducts of square cross section. the Navier–Stokes and energy ...
Bayesian Chemical Mass Balance Method for Surface Water Contaminant Source Apportionment
Publisher: American Society of Civil Engineers
Abstract: A Bayesian chemical mass balance (CMB) source apportionment method is developed using the Markov Chain Monte Carlo (MCMC) approach. Compared with deterministic approaches, the Bayesian method is capable of accounting for ...
Nonlocal Flأ¼gge Shell Model for Vibrations of Double Walled Carbon Nanotubes With Different Boundary Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the vibrational behavior of doublewalled carbon nanotubes (DWCNTs) is studied by a nonlocal elastic shell model. The nonlocal continuum model accounting for the small scale effects encompasses its classical ...
