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, ...
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 ...

Efficient Symmetry Method for Calculating Integral Prestress Modes of Statically Indeterminate Cable-Strut Structures
Publisher: American Society of Civil Engineers
Abstract: Novel statically indeterminate structures generally contain both self-stress modes and internal mechanisms, and have few or no load-bearing capacities before being prestressed. These structures could not maintain stable ...
Feasible Prestress Modes for Cable-Strut Structures with Multiple Self-Stress States Using Particle Swarm Optimization
Publisher: ASCE
Abstract: A prestressed cable-strut structure is usually regarded as a mechanism before being prestressed. Under the action of initial prestresses, the internal infinitesimal mechanisms can be rigidified, resulting in achieving the ...
Fatigue Crack Growth and Control of 14MnNbq Welding Plates Used for Bridges
Publisher: American Society of Civil Engineers
Abstract: The fatigue-crack growth (FCG) behavior of 14MnNbq bridge steel was experimentally investigated in this paper. The fatigue-crack growth rate and threshold under different stress ratios (
