Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...
A Knowledge-Based System for the Damage Assessment of Timber Trusses
A knowledge-based system for the maintenance of over two hundred timber Warren truss buildings is being developed at the Royal Military College of Canada by the Knowledge-Based Expert...
A Study on Aseismic Behaviours of Composite Trussed Arch Bridge
Composite trussed arch bridge is a new type bridge structure developed in China recently, It has the following features: good integrality, reasonable inner force distribution, great spanning...
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
Closing the Loop
The 5.1 mi Cooper River Bridge, the longest in South Carolina, completes the I 526 Mark Clark Expressway around Charleston. It is a two-way, four-lane structure with the capability of...
Local Scour at Bridge Piers in Alberta?Case History
A two span steel truss bridge with a rectangular concrete central pier was built over the Oldman River near Brocket in south-west Alberta in 1954. Initially the bridge was built square...

Structural Characterization of an Articulated-Truss Joint
A first generation space crane articulated-truss joint was statically and dynamically characterized in a configuration which approximated an operational environment. The articulated-truss...
Analysis of Space Crane Articulated-Truss Joints
Three articulated-truss joint concepts for the space crane are studied to evaluate their static structural performance over a range of geometric design parameters. Emphasis is placed on...
Response of Space Structures Under Sudden Local Damage
Damages to space structures can come from such adverse events as impact by foreign objects, docking, drastic temperature changes, and exposure to radiation and charged particles. This...
Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...
Evolution of the Space Station Freedom Module Pattern
The Space Station Freedom (SSF) is being designed to serve as a permanently manned platform in space to accommodate a growing amount of supported scientific research and, ultimately, to...
A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
Calendar: Bridges 1993
Featured bridges are: West Lilac Road Bridge (CA); Pine Bank Arch (NY); South Presa Street Bridge (TX); Peacock Lock (PA); Northampton Bridge (PA); Bridge of the Gods (WA); Main Street...
Damage-Tolerant Design of Deterministic and Nondeterministic Structural Systems
Many structures are exposed to very hazardous environments and they are likely to be damaged during their lifetime. Damage occurrence may cause a dramatic reduction in the safety of structural...
Stochastic Response Analysis of Nonlinear Plane Trusses with Spatial Variability
This study considers responses of geometrically and materially nonlinear plane truss structures with spatially uncertain system parameters, subjected to random excitations. A stochastic...
Limit and Post-Limit Behavior of Space Trusses
A numerical technique for the nonlinear analysis of space trusses taking into consideration such factors as load-eccentricity, initial crookedness of the member and nonlinear stress-strain...
An Adaptive Importance Sampling Strategy
An adaptive importance sampling scheme is presented. The scheme updates both the estimate of system failure probability and the importance sampling density. The sampling density used is...
Effects of Random Errors on Space Station Truss
Results of Monte Carlo simulations of structural responses of a finite element model of a space station truss to random member length imperfections are reported The results reveal that...
Dynamic Behavior of a Non-Linear Cable Truss
The equations of motion of a geometrically non-linear cable truss are presented. The behavior of the truss subject to harmonic excitation is studied....
