Analysis of Blast‐Loaded, Buried RC Arch Response. I: Numerical Approach
Publisher: American Society of Civil Engineers
Abstract: The physical processes that govern the dynamic interaction between a soil continuum and an abutting or embedded structure are very complex and, often, highly nonlinear, requiring a numerical approach for the solution of ...
Radiative Properties of Finite Inhomogeneous Cirrus Clouds: Monte Carlo Simulations
Publisher: American Meteorological Society
Abstract: The Monte Carlo method is used to study the impact of various cloud morphologies (roughness, voids, waves, and horizontal spreading) on radiative properties of finite, thin, model cirrus clouds. The cloud-top reflectance ...
Nonlocal Continuum Damage/Plasticity Model for Impulse‐Loaded RC Beams
Publisher: American Society of Civil Engineers
Abstract: In this paper, a rate‐independent constitutive model for plain concrete is proposed for application to the analysis of impulse‐loaded structural members. The model combines a continuum damage approach, using a scalar damage ...
Limit Analysis of Welded Tee End Connections for Hollow Tubes
Publisher: American Society of Civil Engineers
Abstract: This paper presents a limit analysis, based on the yield line approach, for predicting the ultimate capacity of welded tee end connections for hollow tubes. Five failure mechanisms are identified. The failure mechanisms ...
Strain‐Based Constitutive Model with Mixed Evolution Rules for Concrete
Publisher: American Society of Civil Engineers
Abstract: The theories of continuum damage mechanics and plasticity are combined in a strain‐based phenomenological approach to yield an effective constitutive model for plain concrete. The model reproduces the majority of the typical ...
Progressive Collapse Criteria and Design Approaches Improvement
Publisher: American Society of Civil Engineers
Abstract: Methods for the assessment of structural designs or existing structural systems for susceptibility to disproportionate (progressive) collapse and prescriptive methods intended to mitigate or decrease the likelihood of ...
Analysis of Blast‐Loaded, Buried RC Arch Response. Part II: Application
Publisher: American Society of Civil Engineers
Abstract: A hybrid numerical approach, which combines the finite difference technique and the finite element method, is coupled with a nonlocal continuum damage/plasticity model for plain concrete, a rate‐dependent cap model for ...
The Influence of Inlet Conditions on the Performance of Annular Diffusers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low speed tests have been carried out to investigate the performance and mechanism of flow in two annular diffusers having center bodies of uniform diameter and conically diverging outer walls. ...
Skill Tests and Parametric Statistics for Model Evaluation
Publisher: American Society of Civil Engineers
Abstract: A series of traditional statistical methods and nonparametric skill tests are assembled into a model statistical analysis program (MSAP) with the intent of evaluating their ability to verify surface water models. Using two ...
The Influence of Dilution Hole Geometry on Jet Mixing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements have been made on a fully annular test facility, downstream of a row of heated dilution jets injected normally into a confined crossflow at a momentum flux ratio of 4. The ...
