Laplace-Time Domain Method for Computing Dynamic Response of Linear Systems to Arbitrary Intermittent Loadings
(ASCE, 2020)In evaluating of the response of linear systems to arbitrary intermittent loadings, traditional methods have been exclusively conducted in the time domain where the time resolution must be carefully chosen. In this paper, ... -
3D Grain-Based Mesoscale Modeling of Short Fatigue Crack Growth for Bridge Weldments Considering Crack-Front Evolution
(ASCE, 2020)To evaluate short crack growth and fatigue damage accumulation in steel structures, efforts have been made based on a two-dimensional (2D) grain-based model for fatigue life assessment under variable amplitude loads. ... -
Step-Level Occupant Detection across Different Structures through Footstep-Induced Floor Vibration Using Model Transfer
(ASCE, 2020)This paper presents a floor-vibration-based step-level occupant-detection approach that enables detection across different structures through model transfer. Detecting the occupants through detecting their footsteps ... -
Unified Effective Stress Equation for Soil
(ASCE, 2020)Since the early 2000s, suction stress has been conceptualized as a unitary way to quantify effective stress in soil, i.e., effective stress equal to total stress minus suction stress. Suction stress is the part of ... -
Bounds on Reliability of Larger Systems by Linear Programming with Delayed Column Generation
(ASCE, 2020)In order to accurately assess the reliability of a real-world complex system, the joint distribution of component events is needed. In reality, however, such complete information to model the joint distributions of system ... -
Modeling Deficiencies in the Eight-Node Mindlin Plate Finite Element Physically Explained
(ASCE, 2020)Modeling errors that prevent the eight-node Mindlin plate finite element to behave correctly, namely shear locking and spurious zero-energy modes, can be explained using strain gradient notation. This notation is physically ... -
Bayesian Model Updating Using Modal Data Based on Dynamic Condensation
(ASCE, 2020)This paper introduces a methodology for Bayesian model updating of a linear dynamic system using the modal data that consists of the posterior statistics of the modal properties, identified from dynamic test data using a ... -
DEM Modeling of Grain Size Effect in Brittle Granular Soils
(ASCE, 2020)The size-dependent strength of individual particles controls several key aspects of the constitutive response of brittle granular materials. Capturing this factor in numerical analyses is essential to accurately model the ... -
Wind Velocity Field Simulation Based on Enhanced Closed-Form Solution of Cholesky Decomposition
(ASCE, 2020)The spectral matrix decomposition is a significant task for a wind velocity field simulation. However, the decomposition requires significant computational time and memory for large-scale structures with a large number of ... -
Life-Cycle Cost Evaluation Strategy for High-Performance Control Systems under Uncertainties
(ASCE, 2020)High-performance control systems (HPCSs), including active, hybrid, and semiactive control strategies, can perform over a wide excitation bandwidth and are therefore good candidates for multihazard mitigation. However, the ... -
Characterization of Shear Behavior in Stainless Steel Wire Mesh Using Bias-Extension and Picture Frame Tests
(ASCE, 2020)The main purpose of this paper is to find a suitable method for determining the in-plane shear characteristics of a type of “cellular metal” plain-woven stainless steel wire mesh. That no ready-made standard test exists ... -
Three-Dimensional Analytical Model for Coupled Track-Tunnel-Soil System in a Multilayered Half-Space
(ASCE, 2020)An analytical model is presented in this paper to predict the three-dimensional dynamic response of a circular tunnel in an elastic multilayered half-space. By applying the transfer matrix method and wave transformation, ... -
Data-Driven Computational Homogenization Method Based on Euclidean Bipartite Matching
(ASCE, 2020)Image processing methods combined with scanning techniques—for example, microscopy or microtomography—are now frequently being used for constructing realistic microstructure models that can be used as representative volume ... -
Modeling a Flexible Ring Net with the Discrete Element Method
(ASCE, 2020)Flexible barriers have been proven to be effective measures for mitigating natural hazards, such as rockfalls, gravel flows, and debris flows. This paper presents a new numerical ring model based on the discrete element ... -
Mesoscale Analysis of Fatigue Damage through Aggregate–Mortar Bond Cracks in Cementitious Composites
(ASCE, 2020)A micromechanics-based model is developed to study the fatigue response of cementitious composites. Microcrack growth, which is the predominant mechanism responsible for fatigue damage, is explicitly modeled at the mesoscale. ... -
