Bayesian Reliability Analysis of Structures with Multiple Components
This study develops a method of Bayesian reliability analysis to establish an optimal inspection schedule of structures with multiple components using the data collected during inservice...

Reliability and Redundancy Assessment of Prestressed Truss Bridges
Methods for the assessment of the reliability and redundancy of post-tensioned trusses are suggested. The effect of tendon layout on the reliability and redundancy of post-tensioned trusses...

Unusual Spacecraft Materials
For particularly innovative space exploration missions, unusual requirements are levied on the structural components of the spacecraft. In many cases, the preferred solution is the utilization...

Reliability Estimation for Vertical Lift Gate at Emsworth Dam
The lift gates are composed of two horizontal trusses, two vertical girders, seven diaphragms, and two end frames. A critical element in the structural integrity of the lift gate is a...

Resin Transfer Process Modelling: Computational & Experimental
In most cases, the resin transfer molding (RTM) researcher has a fundamental understanding of composites and possibly some mold design experience. The areas of resin flow dynamics and...

Localization Instabilities Due to Damage and Fracture Propagation: Application to Tensile Specimens
In recent research it has become clear that localization of damage due to strain softening as well as propagation of interactive cracks can result in bifurcations of the loading path characterized...

Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...

Form Follows Geometry
The $107 million NCNB Plaza in Tamps, Fla. consists of a 32 floor, 500,000 sq ft, 455 ft tall office tower; a 40,000 sq ft, 78 ft tall banking hall, and a 280,000 sq ft parking garage...

The Colossus Superstructure
This chapter explores the structural elements of the Colossus....

Fabric Meets Cable
The newest generation of fabric-roofed stadiums are cable domes designed by David H. Geiger of Geiger Gossen Hamilton Liao Engineers, New York City. He also uses the term tensegrity coined...

Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...

Modular Restoration Structures?A Versatile and Cost Effective Transmission Tool
Most electric utilities use a large variety of different types and designs of transmission structures. Because of this, it is not practical or economically justifiable for these utilities...

The Design of Diagonal Cross-Bracing
The results of an analytical and experimental study on the behavior of simple and double diagonal cross-bracings in vertical stiffening trusses and in built-up open web beams are presented...

Manipulation of Shell and Fabric Structure Form
Fabric structures and concrete shells are readily compared because of their curving shapes and the apparent structural derivation of their forms. Every fabric structure includes compression...

Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Major Advances in Finite Element Model Technology
The evolution of finite elements is traced from the viewpoint of finite element shape functions and element-related techniques. Particular emphasis is placed on the isoparametric element,...

Parallel Computations for Automated Finite Element Modeling
This paper discusses initial efforts to combine an automatic mesh generator and element by element solution approaches to produce efficient parallel computational procedures on adaptively,...

NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...

Study of Partially Prestressed Beams With Unbonded Post-Tensioning
Test on partially prestressed members with bonded Post-Tensioning started recently. Experimental information regarding partially prestressed members having unbonded post-tensioning is...

Dynamic Characterization of Posttensioned Rods in Stressed Timber Systems
A new approach is presented to monitor the levels of force in posttensioning rods in stressed timber systems. The dynamic response of the rod under an impact load is characterized and...
