An Adaptive Mixture of Normal-Inverse Gaussian Distributions for Structural Reliability Analysis
(ASCE, 2022-01-13)Recovering the probability distribution of the limit state function is an effective method of structural reliability analysis, in which it still is challenging to balance the precision and computational efforts. This paper ... -
Upper-Bound Solution for the Stability Analysis of Layered Slopes
(ASCE, 2022-01-10)The rotational failure mechanism with a log-spiral is most efficient in upper-bound limit analysis for homogenous slopes, but it cannot work well in regard to layered slopes. In this study, the log-spiral rotational mechanism ... -
Optimal Design for the Blunt Trailing-Edge Profile of Wind Turbine Airfoils under Glaze Ice Conditions
(ASCE, 2022-01-11)Glaze ice is more likely to occur on the rotating blade, and greatly decreases the energy utilization efficiency of wind turbines. Moreover, due to its complex and irregular shape, a high-quality grid and more grid cells ... -
3D Dislocation Density–Based Crystal Plasticity Model for Rock Salt under Different Temperatures and Strain Rates
(ASCE, 2021-12-29)Rock salt is a sedimentary rock found in nature as bedded or domal deposits due to evaporating inland seas or any enclosed bodies of saline water. Rock salt hosts caverns within the underground deposits that can potentially ... -
Adaptive Bayesian Inference Framework for Joint Model and Noise Identification
(ASCE, 2021-12-28)Model updating, the process of inferring a model from data, is prone to the adverse effects of modeling error, which is caused by simplification and idealization assumptions in the mathematical models. In this study, an ... -
Archetype Dynamically Equivalent 3-DOF Model to Evaluate Seismic Performances of Intermediate Discontinuity in Frame Structures
(ASCE, 2022-01-05)This paper investigated an intermediate discontinuity in a frame structure and its capability to mitigate the effects of seismic ground motions. The discontinuity represents a sudden change in the stiffness of the frame. ... -
Bridge Flexibility Identification through a Reference-Free Substructuring Integration Method Driven by Mode Fitting
(ASCE, 2021-12-28)Flexibility plays an important role in bridge load-carrying capacity assessment. The flexibility of bridges has been extracted from the measured data of numerical impact testing and in laboratory experiments. Recently, ... -
Joint Statistics of Natural Frequencies Corresponding to Structural Systems with Singular Random Parameter Matrices
(ASCE, 2022-01-03)An asymptotic approximation methodology for solving standard random eigenvalue problems is generalized herein to account for structural systems with singular random parameter matrices. In this regard, resorting to the ... -
A Temporal Multiscale Model for Fatigue Damage of Concrete
(ASCE, 2021-12-24)A temporal multiscale model was developed to characterize the damage that evolves in concrete structures throughout a complete scenario of dynamic fatigue loading. The damage was decomposed into quasistatic and dynamic ... -
Energy-Based Fracture Criterion of Rock–Concrete Interface Considering Viscoelastic Characteristics
(ASCE, 2021-12-09)To investigate the fracture property of the rock–concrete interface after sustained loading, creep tests were conducted on composite rock–concrete beams with two mechanical grooving interfaces, 4×4 and 7×7 interfaces, under ... -
Mesoscale Investigation of Fine Grain Contribution to Contact Stress in Granular Materials
(ASCE, 2022-01-06)Fine grains play an important role in mechanical properties of granular materials as they control how plastic strain may develop, which has a noticeable impact on mechanical stability. In this work, we use numerical ... -
