RISImproved Symmetry Method for the Mobility of Regular Structures Using Graph Products
Publisher: American Society of Civil Engineers
Abstract: Mobility analysis plays a key role in form finding and design of novel kinematically indeterminate structures. For large-scale or complex structures, it demands considerable computations and analyses, and, thus, efficient ...
Generalized Eigenvalue Analysis of Symmetric Prestressed Structures Using Group Theory
Publisher: American Society of Civil Engineers
Abstract: As conventional approaches for calculating natural frequencies do not make full use of the inherent symmetry of a structure, the rising degree of freedoms often leads to significant increase in computational demand. In ...
Efficient Method for Moore-Penrose Inverse Problems Involving Symmetric Structures Based on Group Theory
Publisher: American Society of Civil Engineers
Abstract: The Moore-Penrose inverse has many applications in civil engineering, such as structural control, nonlinear buckling, and form-finding. However, solving the generalized inverse requires ample computational resources, ...
Simultaneous Determination of Critical Slip Surface and Reliability Index for Slopes
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new method for applying reliability-based design approaches to slope stability analysis. In this method the soil properties are considered to be random variables. The factor of safety of the slope is ...
Novel Form-Finding of Tensegrity Structures Using Ant Colony Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tensegrity structures have remarkable configurations and are drawing the attention of architects and engineers. They possess inextensional mechanisms and self-stress states at a static equilibrium ...
Centrifugal and Numerical Modeling of a Reinforced Lime-Stabilized Soil Embankment on Soft Clay with Wick Drains
Publisher: American Society of Civil Engineers
Abstract: A centrifuge test was performed on a reinforced embankment backfilled with lime-stabilized soil on soft clay installed with wick drains. The finite-element program PLAXIS was employed to simulate the centrifuge test on the ...
Investigation of Soil Arching under Cyclic Loading Using the Discrete Element Method
Publisher: ASCE
Abstract: This paper presents an analysis of the soil arching effect associated with piled embankments under cyclic loading by developing a series of two-dimensional trapdoor discrete numerical models. After identification of the ...
Interaction of Soil Arching under Trapdoor Condition: Insights from 2D Discrete-Element Analysis
Publisher: ASCE
Abstract: The trapdoor/trapdoor-like model test has been widely utilized to investigate the evolution of soil arching. However, the primary focus of previous studies has been on the mechanical and deformation behaviors of the arching ...
Three-Dimensional Discrete-Element-Method Analysis of Behavior of Geogrid-Reinforced Sand Foundations under Strip Footing
Publisher: ASCE
Abstract: This paper presents a three-dimensional discrete numerical analysis associated with the interaction of geogrid and surrounding soils in geogrid-reinforced sand foundations under strip footing. After validating the numerical ...
