Lateral Bracing of Plate Girders Using Deck Forms
The initial results of a study of the ability of stay-in-place steel deck forms to stabilize bridge girders during construction is presented. The analytical and experimental results to...

Long Life Fatigue Behavior of Welded Steel-Bridge Girder Details
The Federal Highway Administration is nearing completion of a five year, 1.5 million dollar effort titled 'Variable Amplitude Load Fatigue' to investigate the behavior of welded bridge...

Inelastic Bridge Rating Procedures for Steel-Girder Bridges
Current bridge rating procedures for steel beam and girder bridges ignore the ability of the structure to redistribute forces both longitudinally and laterally. When rating steel bridges...

Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...

Influence of Diaphragms on the Overall Performance of Bridges
Field data collected during vehicular loading has been used to evaluate the performance of diaphragms in composite steel plate girder bridges. This has included comparisons with finite...

Physical Testing of Two R/C Skewed Slab Bridges with Integral Wall Abutments
Two one-third scale models of an existing reinforced concrete skewed slab bridge with integral wall abutments were tested statically to failure. Typically, these bridges are designed using...

NDE of Steel Bridges by Acoustic Emission
Acoustic emission technique (AE) was used to investigate fatigue cracking phenomenon during a series of laboratory tests of various bridge steels and during field testing of an in-service...

Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...

Nondestructive Evaluation of Timber
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining...

Proof Loads in LRFD Format for Bridge Evaluation
Proof load testing is considered as a reliable approach to evaluation of an existing structure's load-carrying capacity. It can be effectively used for highway bridge evaluation, to either...

Reliability of Highway Bridge Piers
Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at...

Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...

After-Fracture Response of a Two-Girder Steel Bridge
The I-40 bridges over the Rio Grande are due to be razed in mid 1993 due to geometry and traffic safety considerations. The bridges are classified as 'fracture critical' two girder steel...

Modal Analysis Technique for Bridge Damage Detection
The dynamic responses of a wide-flange steel beam with artificially introduced cracks were studied analytically and experimentally. Frequencies, displacement mode shapes (DMS) and strain...

Correction Factor Method for Building Analysis Under Sequential Dead Loads
The effect of the sequential application of dead load due to the sequential nature of construction is an important factor to be considered in the multistory frame analysis. One of the...

An Efficient Analysis of Framed-Tube Structures
An efficient model for analysis of framed-tube systems is proposed in this study. The proposed model can represent the interaction between plane frames consisting the tube system. Analysis...

Dynamic Inelastic Analysis of Tall Buildings
Members with undesirably early formed plastic hinges as well as excessive conservatism introduced in the preliminary design of tall buildings can be identified by the behavior state study...

Optimal Design of Building Structures Using the Predetermined Sections
A practical optimization algorithm for the member design of building structure is presented in this paper. The emphasis is particularly concentrated on the practical applicability of the...

Reliability-Based Design of Transmission Towers Under Wind and Ice Loadings
This study suggests a practical but rational approach for the development of reliability-based LRFD criteria for transmission towers under wind and ice loadings in Korea. Based on available...

Floor Response Spectra Analysis Including Correlations of Multiple Support Motions
