The Truss-Beam and Space Technology
A method is presented herein to determine the dynamic characteristics of truss-beam systems for both planar and space structures. Results from this approach are compared with those of...
Reliability Estimation for Vertical Lift Gate at Emsworth Dam
The lift gates are composed of two horizontal trusses, two vertical girders, seven diaphragms, and two end frames. A critical element in the structural integrity of the lift gate is a...
Stochastic Finite Element Analysis of Metal Plate Connected Wood Trusses
A stochastic finite element approach is developed for use in ananlyzing metal plate connected wood trusses. The procedure uses linear beam-column elements to model the wood members. The...
Space Station Truss Longevity
This paper describes the approaches taken to ensure Space Station truss longevity. The expected environmental and operational threats to structural integrity and the specific solutions...
The Covered Wooden Truss Bridge
Toronto Skydome Retractable Roof Stadium—The Roof Concept and Design
The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof,...
The Design of Diagonal Cross-Bracing
The results of an analytical and experimental study on the behavior of simple and double diagonal cross-bracings in vertical stiffening trusses and in built-up open web beams are presented...
Space Frame Experimental Behavior
Previous tests on double layer grid space frames have shown that, in some cases, significant initial forces exist. In addition, for externally determinate symmetrical tests, there was...
Composite Floor Vibrations: Predicted and Measured
Several steel composite floor systems of relatively long span trusses for a number of high rise structures in the Chicago area have been subjected to field measurements to evaluate their...
Hysteresis Studies Including Post Buckling of Angle Web-Members for Truss-Type Girders
The paper presents analytical studies of the buckling capacities and hysteresis behavior of angle-web members of truss-type girders. The eccentricity between the loading point and the...
A Study of the Precision of Optimum Design Using Suboptimization
As the scale of structures becomes larger and their configuration become more complicated, the design variables and constraint conditions increase, and numerical calculation of the optimum...
Total Optimization of Truss Considering Shape, Material and Sizing Variables
A total optimum design method is developed for truss structures in which the shape of the structure, discrete material kinds and cross-sectional areas of member elements are optimized...
Optimization for Exact Stability of 2-Bar Trusses
This paper is concerned with the structural optimization problem of minimizing the weight of a 2-bar truss subject to nonlinear stability constraints. Optimization problems for stability...
Wind Tunnel Testing of the Karnali River Bridge
An extended wind tunnel testing program of the erection procedures and the stability of the completed one-tower cable-stayed Karnali River Bridge was conducted with the help of full bridge...
Aerodynamic Stability of Long Span Suspension Bridge—Effects of Stiffening Truss Width
This paper presents the effects of truss width upon the aerodynamic stability of the long span suspension bridge with truss girder up to 2000 m. It was found that the truss width had a...
Discrete Field Stability Analysis of Latticed Towers
The design of latticed towers is often controlled by the stability of the overall system as opposed to local member buckling. The purpose of this paper is to develop an elastic stability...
A Computational Algorithm to Determine Influence Lines
ERTSYS: An Epoxy Repair of Timber Expert System
Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...
