RISEffect of OCR and Pile Diameter on Load Movement Response of Piles Embedded in Clay over Time
Publisher: ASCE
Abstract: The main causes of soil setup effects on pile response are generation of excess pore water pressure (EPWP) due to installation of prefabricated piles in saturated soils and subsequent dissipation of EPWP and, hence, stress ...
Numerical Investigation of the Load Movement and Ultimate Load of Energy Piles Embedded in Sand
Publisher: ASCE
Abstract: Even though the energy pile is known as an efficient dual-purpose system nowadays, the interactive response under simultaneous mechanical and thermal loads requires further investigation. An attempt has been made to evaluate ...
Cyclic Simple-Shear Behavior of Sand-Steel Interfaces under Constant Normal Stiffness Condition
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental investigation on the cyclic behavior of a sand-steel interface under constant normal stress and normal stiffness conditions. The experiments were performed by using an ...
Effect of Stress Rotation and Intermediate Stress Ratio on Monotonic Behavior of Granulated Rubber–Sand Mixtures
Publisher: ASCE
Abstract: The rotational failure of backfills and embankments is known to be involved with inhering anisotropic effects resulting from different stress paths along the rotational shear plane. The granulated rubber–sand mixtures have ...
Online Policy Iteration-Based Tracking Control of Four Wheeled Omni-Directional Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, online policy iteration reinforcement learning (RL) algorithm is proposed for motion control of four wheeled omni-directional robots. The algorithm solves the linear quadratic tracking (LQT) problem in an ...
Position and Current Control of an Interior Permanent Magnet Synchronous Motor by Using Loop Shaping Methodology: Blending of H∠Mixed Sensitivity Problem and T–S Fuzzy Model Scheme
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a robust mixedsensitivity H∠controller design via loopshaping methodology for a class of multipleinput multipleoutput (MIMO) uncertain nonlinear systems. In order to design this controller, the ...
Effect of Surcharge Pressure on Pile Static Axial Load Test Results
Publisher: American Society of Civil Engineers
Abstract: This paper presents the effect of surcharge support pressure on pile load–settlement response during static load testing. A three-dimensional nonlinear finite-element model is developed to investigate the loading sequences ...
Damage Severity Quantification Using Wavelet Packet Transform and Peak Picking Method
Publisher: ASCE
Abstract: This article aims to present the results of an investigation on detection and quantification of damage location and severity for steel structures using wavelet packet transform for denoising the initial signals, in combination ...
Bidirectional Shear Wave Velocity Measurements to Track Fabric Anisotropy Evolution of a Crushed Silica Sand during Shearing
Publisher: ASCE
Abstract: Continuous bidirectional shear wave velocity measurements were performed in the vertical (V) and horizontal (H) directions to characterize fabric evolution of triaxial soil specimens during shear, wherein, in addition to ...
Prediction of Undrained Behavior of Isotropically and Anisotropically Consolidated Firoozkuh Sand: Instability and Flow Liquefaction
Publisher: American Society of Civil Engineers
Abstract: Recent experimental findings highlight the impact of anisotropic consolidation on triggering flow liquefaction failures. Results of a series of undrained tests on isotropic and anisotropic consolidated Firoozkuh sand are ...
