Condition Assessment of Highway Bridges
An application of modal testing and structural identification in the condition assessment of bridges is presented. Damage definition and conceptualization is discussed. Damage detection...

Bridge Evaluation Using a Hybrid Information System
The objective of this paper is to discuss the developments and implementation of a hybrid system consisting of a rule-based information system and hypermedia technology for use by inspectors...

Seismic Study of a Cable-Stayed Bridge
The focus of this paper is to investigate the non-linear and linear behavior of a cable-stayed bridge in a seismic environment. Three design features of a cable-stayed bridge are studied:...

Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...

Aesthetic Issues in Timber Bridges
The vocabulary of visual design and several generally accepted major principles of visual design are reviewed in order to provide a 'context' for case studies of award-winning timber bridges....

Development of Hardwood Glulam Timber Bridge Standards
Design standards and specification for 5.5 to 27.4 m(18 to 90 ft.) clear span hardwood glued laminated (glulam) highway bridges have been developed and are available from the Pennsylvania...

Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...

Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...

Acoustic Emission Monitoring of Steel Bridges
Global nondestructive monitoring techniques are of great significance for rapid monitoring of bridges. One promising technique involves monitoring the microseismic events (Acoustic Emissions,...

Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...

A Design for a Football Stadium Roof Enabling Growth of a Natural Grass Playing Surface: Sydney Football Stadium - Australia
This paper discusses the development of a design for a stadium roof which will provide conditions allowing the growth of a wearable natural grass surface suitable for sports including...

Phoenix Central Library: Reading Room Roof
This paper discusses the design and analysis of the cable truss roof over the fifth floor reading room of the new Phoenix Central Library. Forty pairs of diagonally oriented cable trusses...

Deployable Mesh Reflector
This paper presents a new deployable reflector for space applications, based on a deployable edge frame that deploys and prestresses a 'rigid' cable network. The edge frame consists of...

Design of Half-Through or Pony Truss Bridges Using Square or Rectangular Hollow Structural Sections
The initial part of this paper will outline some of the research, testing, and investigation which has been done on half-through truss bridges. This research is primarily concerned with...

Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities
Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...

Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...

Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...

Optimal Design Conception of Grid Domes in Practice
In this paper, the optimal design conception of grid domes in practice is presented. The classical dome shell structures covering some irregular boundaries often seems not to be satisfied...

The Georgia Dome and Beyond: Achieving Lightweight - Longspan Structures
In the last two decades, the development of longspan roof structures has undergone a quantum leap. The introduction of steel structures, fabric structures, Bucky Fuller's tensegrity structure,...

Georgia Dome Cable Roof Construction Techniques
This paper will provide a case study of the construction of the Hypar-Tensegrity Cable Roof for the Georgia Dome. The paper will emphasize innovative computer analysis of the construction...
