Structural Integrity of Space Trusses
Space trusses of the double layer grid configuration can experience rapid propagation of failure in the ultimate load condition and thus are potentially vulnerable to progressive collapse...
Optimization of Space Lattice Structures with Multimodal Frequency Constraints
The paper presents an optimization algorithm for the design of space trusses subjected to constant value constraint. The goal of the optimization is a structure of the highest multiple...
Large Deformation Analysis of Lattice Truss Structures Including Hysteretic Material Behavior
A methodology is presented to analyze lattice truss structures including both material and geometric nonlinearities. Modeled member material behavior modes include: buckling, yielding,...
Collapse Behavior of Double-Layer Space Truss Grids with Member Buckling
The results of collapse tests of over twenty space truss grids with elastic buckling of members are reviewed. The space truss grids include three types, that is, square-on-square, square-on-diagonal...
Seismic Performance and Retrofit of the Golden Gate Bridge
Since its opening in 1937, the Golden Gate Bridge has endured and functions as an important transportation link for Bay Area commerce and commuters. After an earthquake in 1989, T.Y. Lin...
Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...
Design and Construction of the Cable-Stayed Wooden Space Truss Roof
The thinning must be enforced for healthy development of an artificial forest. The most effective use of thinning lumber is construct of the space truss structure. This election systems...
Structural Analysis for Structural Design
This paper presents a simple extension to conventional structural analysis that serves to provide additional information that is of significant use to the structural design process. Specifically,...
Multiobjective Optimization of Actively Controlled Structures
A general methodology is presented for the multiobjective optimization of actively controlled structures. The methodology can handle structures involving precise as well as fuzzy data....
Modeling to Generate Alternatives in Discrete Structural Optimization
Structural design, like other complex decision problems, involves many trade-offs among competing criteria. While mathematical programming models are increasingly realistic, there are...
Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...
Evolutionary Methods for Synthesis of Truss Topology
Performance of Metal-Plate-Connected Wood Truss Roof Systems During Hurricane Andrew
The New Clark Bridge: Saddle-Draped Cables
The new $85 million, 108 ft wide Clark-Bridge replaces a 20 ft wide 1928 truss bridge at Alton, Ill., carrying US 67 over the Mississippi about one mile above the recently completed Lock...
Inspection and Repair of a Timber Truss Bridge - An Application of Nondestructive Testing
Columnless in Chicago
The United Center in Chicago is now home to the Bulls basketball team and the Blackhawks hockey team. The arena features luxury suites, a column-free interior and unobstructed views. An...
Historic Yorktown: New Bridge Keeps Old Design
In historic Yorktown, Va., the best solution to reconstructing an obsolete 1952 bridge was to keep its unique design while widening it for '90s traffic. Like the original,...
Space-Frame Pyramid
The world's largest space frame pyramid, completed at California State University in Long Beach in late 1994, proved to be a lighter weight and more economical alternative...
Bridge to the Future
The experimental Roize Bridge, near Grenoble, France, features an innovative composite space truss and unique modular construction methods for efficiency and economy. The Roize Bridge...
Fast-Track Stadium
The project team selected to design and construct Egypt's cable-supported Cairo Stadium Indoor Sports Complex in late 1989 faced a hard-and-fast deadline. Just 18 months later,...
