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...
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...
Space Frame Solution for the Design of Large Pyramid Structures
This paper presents the engineering design methodology, structural analysis, system detailing, and installation procedures for a large span space frame structure currently under construction...
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...
Response of Truss Structures Subjected to Dynamic Loads During Member Failure
The paper presents a method for and results from an investigation of the response of a truss structure during the chain reaction of its member failure while subjected to external static...
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...
Design of Low Rise Dome for the University of Hawaii at Manoa
The 97.5m span dome covering the new multipurpose sports arena at the University of Hawaii in Manoa is a spherical, triangulated dome structure with a rise of 16.2m. In addition to the...
Analysis and Design of a Double Layer Barrel Vault with a Large Span
The roof of coal storage in JiaXin Power Station is a double-layer barrel vault. This roof covers span of 103.5 M and a longitudinal span of 88.0 M. The height of this space truss is 3.5...
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...
