Ambient Vibration Survey: Sunshine Skyway Bridge
An ambient vibration survey of the Sunshine Skyway Bridge was performed. The goal of this survey was to provide field data on the dynamic characteristics of the structure to corroborate...

An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...

Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...

Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures
As with other forms of infrastructure, there is an ever increasing need to repair and strengthen unbonded post-tensioned concrete structures. Repairs may be necessitated for a variety...

HUD Concerns: Post-Tensioned Foundations in Texas
An investigation was conducted of post-tensioned slab foundation systems in Texas pursuant to a request from the Headquarters Office's of the U.S. Department of Housing and Urban Development...

Investigation of Full-Scale Performance of Structures—Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...

Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...

The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...

Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...

Comparative Evaluation of Plasticity Theories Against Tension-Torsion Test at Finite Strain
This paper investigates and evaluates three hardening theories against a variety of nonproportional loading experiments on tubes made of annealed copper. It was concluded that the isotropic...

Failure Analysis of Masonry Structures
The use of smeared-crack and interface elements for the analysis of masonry structures is investigated. While a variety of structural problems can be solved with a combination of both...

Qualitative Evaluation of Preliminary Structural Designs

Analysis of the Georgia Dome Cable Roof

Tensile-Integrity Structural Concepts for the Lunar Surface
This paper suggests the use of tension cable structures of a particular type, Tensegrity structures, for a lunar base. Tensegric shells can be a system of bars and cable net. The shell...

Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...

Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...

In-Plane Non-Linear Random Vibration of Composite Plates
Filamentary composite structural components used in engineering applications are usually subjected to stochastic loads. Composites have strongly anisotropic properties and display significantly...

A Statistical Method for the Reliability of Mechanical Components
The usual statistical treatment of data for the reliability of components is to fit a distribution to them and then to use this theoretical distribution for predictions. But since this...

On a Procedure to Estimate the Reliability of Mechanical Components
A procedure, based on the response surface concept is suggested to estimate the failure probability of mechanical components and structures under static as well as dynamic loading conditions....

TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
