RISRapid Controllable Damper Design for Complex Structures with a Hybrid Reduced-Order Modeling/Simulation Approach
Publisher: American Society of Civil Engineers
Abstract: Evaluating controllable damping designs typically requires simulation of the resulting inherently nonlinear closed-loop system because linear design strategies cannot always be reliably used. These analyses typically require ...
Unified Anisotropic Elastoplastic Model for Sand
Publisher: American Society of Civil Engineers
Abstract: This paper presents a unified approach to model the influence of fabric anisotropy and its evolution on both the elastic and plastic responses of sand. A physically based fabric tensor is employed to characterize the ...
Correction for Flexural Vibration Analysis in Nonlocal Timoshenko Beams with Initial Stress
Publisher: American Society of Civil Engineers
Abstract: In the present work, the flexural vibration of nonlocal Timoshenko beams under an initial stress is readdressed. The complete effect of the initial stress is taken into account in the basic formulation. The analytical ...
STRIDE for Structural Identification Using Expectation Maximization: Iterative Output-Only Method for Modal Identification
Publisher: American Society of Civil Engineers
Abstract: This paper introduces structural identification using expectation maximization (STRIDE), a novel application of the expectation maximization (EM) algorithm and approach for output-only modal identification. The EM algorithm ...
Detection of Sinkhole Formation by Strain Profile Measurements Using BOTDR: Simulation Study
Publisher: American Society of Civil Engineers
Abstract: The sudden collapse of sinkholes in the Dead Sea area represents a serious threat to infrastructure in the area. The formation of these sinkholes has been shown to be directly correlated with the drop in the Dead Sea water ...
Bio-Inspired Passive Optimized Base-Isolation System for Seismic Mitigation of Building Structures
Publisher: American Society of Civil Engineers
Abstract: An energy dissipation mechanism of abalone shells, called sacrificial bonds and hidden length, is simulated and proposed to develop new strategies for base isolation. The concept of integrating this novel energy dispersion ...
Flat Cavity Expansion: Theoretical Model and Application to the Interpretation of the Flat Dilatometer Test
Publisher: American Society of Civil Engineers
Abstract: This paper presents a theoretical model for flat cavity expansion in elastic soil. By using the conformal mapping method, the nonaxisymmetric boundary value problem of flat cavity expansion is transformed from the original ...
Statistical Damage Prognosis for In-Service Civil Structures against Hazards: Formulations and Applications
Publisher: American Society of Civil Engineers
Abstract: This paper proposes an expectation-maximization (EM) algorithm embedded statistical damage prognosis paradigm for in-service civil structures against natural hazards. Being within the scope of structural health monitoring, ...
Stress-Dependent Electrical Contact Resistance at Fractal Rough Surfaces
Publisher: American Society of Civil Engineers
Abstract: The electrical contact resistance between contacting rough surfaces was studied under various compressive stresses. The samples considered here were isotropically roughened aluminium disks with upper and lower surfaces ...
Monocular Computer Vision Method for the Experimental Study of Three-Dimensional Rocking Motion
Publisher: American Society of Civil Engineers
Abstract: The rocking problem is applicable to a wide variety of structural and nonstructural elements. The current applications range from bridge pier and shallow footing design to hospital and data center equipment, even art ...
