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...
An Information System on the Performance of Suspension Bridges Under Wind Loads
While most suspension bridges for which information is available, in operation between the period: 1701-1992, have performed satisfactorily under wind loads, a few bridges were destroyed,...
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...
Full-Scale Bridge Test to Monitor Vibrational Signatures
A full-scale highway bridge, in the process of being demolished and replaced was monitored using vibrational techniques in its in-service condition. The bottom flange and web of one fascia...

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
This paper deals with the response spectrum analysis method of the secondary structures including the correlation effects between nonuniform support excitations. Based on the random vibration...
Damage Estimation of Existing Bridge Structures
During recent earthquakes, severe damage have been reported in many bridge structures. Regardless of many damaged structures, methods to identify damage of structures are still limited...
Development of an Improved Rapid Seismic Analysis Procedure
New developments in computer capabilities and lessons learned from recent earthquakes have facilitated improvement of the Rapid Seismic Analysis Procedure (RSAP) currently specified in...
New Views for Modeling Dynamic Response of URM Buildings
Various computational models are used to depict seismic response of an unreinforced masonry building that was subjected to the 1989 Loma Prieta Earthquake. The worthiness of various analytical...
Finite Element Analysis of a Highway Bridge Hinge
A highway bridge hinge is a very important element in bridge design. It releases thermal stresses that may be developed in the superstructure or the substructure of a bridge. A common...
Seismic Design of Steel Beam-to-Box Column Connections
This paper is a study of the ductility requirements of steel beam-to-box column connections using the bolted beam web and welded beam flange details. Since the beam moment at the connection...
Behavior and Design of Angle Connections Subjected to Cyclic Axial Force and Shear
The objectives of this study were to establish cyclic behavior of double angle shear connections subjected to axial load and to develop design recommendations. Five cyclic tests of double...
Recent Successes in Welding Jumbo Shapes
A rather unique structure utilizing jumbo shapes was recently designed and fabricated. The structure was 100% welded according to the specifications for welding jumbo shapes recently developed...
Inelastic Behavior of Noncompact Steel Bridge Girders
This paper highlights the results from one of several finite element studies of the inelastic moment-rotation behavior of continuous-span non-compact bridge girders at interior-pier locations....
Design Property Values of Wood-Based Materials in LRFD Format
