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...

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...

Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...

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...

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...

Akashi-Kaikyo Bridge Underconstruction
This paper presents 1) brief history of the survey work, 2) brief description of the physical dimensions and structural system, 3) major studies for the design, 4) development of higher...

The Structuring of a New Architectural Landscape
Structure plays an increasingly important role in the language of architecture design. Examples from the 2nd half of the 20th century, including transportation systems and buildings, sport...

Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...

Recent Advances in Engineering Design Methodologies
The paper illustrates the mode of operation of the Engineering Design Research Center (EDRC) at Carnegie Mellon University by describing a number of EDRC projects related to structural...

Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...

Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...

EPA's Environmental Monitoring and Assessment Program: Availability of Broad-Scale Environmental Data and Opportunities for Use in Environmental Modeling Applications
The Environmental Monitoring and Assessment and Program (EMAP) has collected a suite of environmental data over a four year period from estuarine systems in the mid-Atlantic and Gulf of...

Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...

Picturing Pollution
Kevin G. Coulton is a professional engineer and photographer who sees in the iridescent sheen of an oil slick on a rainy street a novel way to increase public awareness of water pollution...
