RISA Novel Internal Model-Based Tracking Control for a Class of Linear Time-Varying Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a novel method of constructing an internal model-based design of reference tracking and/or disturbance rejection for a class of linear time-varying plants with a known linear ...
Nonlocal Equivalent Continua for Buckling and Vibration Analyses of Microstructured Beams
Publisher: American Society of Civil Engineers
Abstract: This paper is focused on the buckling and the vibration analyses of microstructured structural elements, i.e., elements composed of repetitive structural cells. The relationship between the discrete and the equivalent ...

Modified Equivalent-Area Method for Calculating Factors of Safety against Deep-Seated Failure of Embankments over Deep-Mixed Foundations
Publisher: ASCE
Abstract: The limit equilibrium method (LEM) and the finite-element method (FEM) commonly have been used in design to calculate the factors of safety (FS) against deep-seated failure of deep-mixed (DM) column-supported embankments ...
A Model of Undrained Stress–Strain Curves Considering Stress Path and Strain Softening
Publisher: ASCE
Abstract: The stress path and strain-softening effect have a great influence on the strength and deformation of soils. Former test results show that the strength and deformation behaviors under lateral unloading conditions are quite ...
Micromechanical Modeling on Compressive Behavior of Foamed Concrete
Publisher: ASCE
Abstract: Much attention has recently been paid to investigating the internal mechanisms between the void structures of foamed concrete and its mechanical behavior. This study adopted the X-ray computed tomography (X-CT) technique ...
Rheological Consolidation of Partially Penetrated Deep Mixed Column-Reinforced Soft Soil under Rigid Foundation
Publisher: ASCE
Abstract: Deep mixed (DM) columns are being increasingly used in regions that host thick saturated soft clays. Under such geotechnical conditions, partially penetrated DM columns are predominantly designed to improve shallow ...
Mesostructure of Foamed Cement Paste and Its Influence on Macromechanical Behavior
Publisher: ASCE
Abstract: Foamed cement paste has been used increasingly as a backfill material in geotechnical engineering applications, such as embankments, tunnels, and retaining walls. However, limited studies have focused on the influence of ...
Performance Tests on Pressure-Dispersed Compression Anchors in Cohesive Soils
Publisher: ASCE
Abstract: Pressure-dispersed compression anchor consists of several anchor units fitted with an end plate. Limited field tests have been conducted to investigate the performance of a pressure-dispersed compression anchor system in ...
Dynamic Stability Analysis of Pile Foundation under Wave Load
Publisher: ASCE
Abstract: The main load on a pile foundation in the ocean is the wave load. Presently, few reports exist on the dynamic stability of pile foundations in the ocean. This paper investigated the dynamic stability of pile foundations ...
