Variational Principles and Explicit Finite-Element Formulations for the Dynamic Analysis of Partial-Interaction Composite Beams
(ASCE, 2020)In this paper, we conduct a systematic dynamic investigation of partial-interaction composite beams under various sophisticated loading conditions that have seldom been presented in the literature. For the purpose of easy ... -
Spherical Hankel-Based Creep Analysis of Time-Dependent Materials Using Boundary-Element Theories
(ASCE, 2020)In this article, the boundary-element method (BEM) is applied to solve viscoelastic problems with any alteration in load, time, or boundary condition. The innovation of using spherical Hankel element framework instead of ... -
Vibration Attenuation and Amplification of One-Dimensional Uncoupled and Coupled Systems with Optimal Metafoundations
(ASCE, 2020)Finite locally resonant metafoundations represent an innovative solution for structural seismic response mitigation based on their filtering capabilities at selected frequency ranges. They inherit the filtering properties ... -
General Solutions for Hydromagnetic Flow of Viscous Fluids between Horizontal Parallel Plates through Porous Medium
(ASCE, 2020)Analytical solutions for the hydromagnetic flow of incompressible viscous fluids between two infinite horizontal parallel plates, with the lower plate moving in its plane with an arbitrary velocity, are established in the ... -
Analytical Solutions for Deep-Buried Lined Tunnels Considering Longitudinal Discontinuous Excavation in Rheological Rock Mass
(ASCE, 2020)For tunneling in a deep, soft rock mass, rock deformation and lining pressure, which are time-dependent behaviors, are mainly affected by rock rheology and longitudinal excavation processes. In practice, tunneling operations ... -
Error Analysis of Multivariate Wind Field Simulated by Interpolation-Enhanced Spectral Representation Method
(ASCE, 2020)An interpolation-based technique can effectively reduce the computational demand involved in a traditional simulation of the multivariate wind field utilizing the spectral representation method (SRM). However, errors are ... -
Dynamic and Seismic Protection of Rigid-Block-Like Elements and Structures on Deformable Ground with Mass-Damper Dynamic Absorbers
(ASCE, 2020)Some elements and structures can be modeled as rigid blocks. To reduce their likelihood of overturning such block-like elements, structures can be coupled with safety devices. In this paper, a model of a rigid block placed ... -
Particle Image Velocimetry Measurements of Bed-Shear Stress Induced By Wall-Bounded Swirling Jets
(ASCE, 2020)This study presents measurements of the bed shear stress associated with the three-dimensional boundary layer induced by a wall-bounded swirling jet. The velocity profile within the viscous sublayer was measured in detail ... -
Assessment of a Hyperbolic Model for Undrained-Cyclic Shearing of Remolded Clay
(ASCE, 2020)The behavior of remolded kaolin clay is examined using cyclic triaxial and resonant column tests. The damping of kaolin is shown to be largely hysteretic, and its cyclic degradation behavior is affected predominantly by ... -
Constructing a Site-Specific Multivariate Probability Distribution Using Sparse, Incomplete, and Spatially Variable (MUSIC-X) Data
(ASCE, 2020)It is important to be able to construct a site-specific multivariate probability density function (PDF) of soil parameters based on limited and incomplete site-specific investigation data alone. This allows the unique ... -
Methodology for Regularization of Force-Based Elements to Model Reinforced Concrete Columns with Short Lap Splices
(ASCE, 2020)In reinforced concrete structures built before the 1970s, it was common for columns to be constructed with short lap splices and widely spaced transverse bars at the column base, leading to increased likelihoods of pull-out ... -
Triaxial Constitutive Law for Ultra-High-Performance Concrete and Other Fiber-Reinforced Cementitious Materials
(ASCE, 2020)This paper presents a triaxial constitutive model for fiber-reinforced cementitious materials (FRCM), with an emphasis on ultra-high-performance concrete (UHPC). The model accounts for the multiaxial stress-strain behavior ... -
Design of Nonlinear Tuned Mass Damper by Using the Harmonic Balance Method
(ASCE, 2020)As a passive control device, tuned mass dampers (TMDs) are widely used in structural vibration control. Due to the nonlinear characteristics of a TMD, it is important to consider nonlinearity in the design process. In this ... -
Analytical and Experimental Investigation of the Behavior of a Rocking Masonry Tuff Wall
