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...
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...
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...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
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...
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...
Nonlinear Dynamic Analysis of Single Point Moored Buoy Under Wave and Current Loadings
In this study, a single point moored spherical buoy under wave and current loadings is analyzed in the time domain considering time memory effects. Geometric nonlinearity of the mooring...
Buckling of Guyed Towers
The buckling load of a column guyed in a plane by symmetric guy wires is considered. The column is built-in at the ground, supported at the top by guy wires, and is loaded by a vertical...
Buckling of Cylindrical Storage Tanks Due to Unsymmetric Lateral Wind Load
Non-linear finite element analysis is used to study the elastic stability of cylindrical storage tanks subjected to unsymmetrical loads. These cylindrical shells are assumed to be fixed...
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...
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...
Interaction Between Beam and Steel Connections
The overall objective of the investigation is to study the behavior of a particular steel connection type, flush end plate steel connections, subjected to shear, axial forces, and possibly...
Design Property Values of Wood-Based Materials in LRFD Format
The development of a U.S. Load & Resistance Factored Design (LRFD) specification and supporting documents for engineered wood construction is nearing completion. The two key components...
Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....
Wood Diaphragm Design Capacities in LRFD Format
Wood diaphragms (horizontal and vertical) have performed well in resisting and transferring lateral forces imposed by major wind and seismic events. Resilient (ductile) behavior of wood...
System Factors in LRFD Format: A Multidimensional Judgment Call
A Load & Resistant Factor Design Specification for wood buildings is being completed. The Specification contains several revisions from the traditional 'repetitive member' factor...
Wood Bridge Design Using AASHTO LRFD Specifications
A nationwide project to develop a load and resistance factor (LRFD) design edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications...
Serviceability Reliability Analysis of Wood Beams
The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the...
