Steel Boxes Carry Rail Lines
Steel box girders plus novel bearing details led to beautiful curved bridges carrying Chicago Transit Authority trains into its Howard Yard. During preliminary design three alternative...
Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...
Steel Plate Girder Alternate I-10/I-17 Interchange
The scope of the Phoenix I-10 Viaduct allowed extensive study for the optimization of this moderate span steel plate girder bridge. The value engineering studies lead to the use of the...
Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...
Prediction and Control of the Wind Response of Long-Span Bridges with Plate Girder Decks
The aerodynamic stability of plate girder decks and methods of improving it are discussed. The selection of an appropriate design wind speed for flutter is reviewed including the effect...
The Far? Bridge?Long Life at Low Costs
The superstructure of the bridge is a steel structure which proved to be competitive compared to the tendered concrete solution, due to simple and rational design both structurally and...
Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...
A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...
Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...
Multiple Bolt Row Moment End-Plates
This paper presents a portion of the results of a study to develop design procedures for the extended, multiple row, moment end-plate configuration. This configuration is used in steel...
Fracture-Mechanics-Based Fatigue Life Estimate
Fatigue lives of tee-shaped weldments are estimated using fracture mechanics concepts and crack growth rate data. Fracture mechanics is used to develop an approximate expression for stress...
The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...
Artist in Wood Structures
Julius Natterer is chairman on the Institute for Wood Structures at the Federal Institute of Technology in Lausanne, Switzerland, and designer of more unusual or unique wood structures...
Fish Screens for Hydropower Developments
The paper reviews five screening systems that are now being used at hydropower developments. The screen types discussed have a demonstrated ability to meet agency fish screening criteria....
Heterosis Shell Element in GTSTRUDL
The most popular shell finite element is the degenerated solid type, originally formulated to model thick shells. However, in thin shell applications, this element fails by 'locking'....
Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...
Nonlinear Dynamic Response ofWindow Glass Plates Using Finite Difference Method
C. V. G. Vallabhan has established an efficient iterative procedure to solve the Von Karman nonlinear plate equations using finite difference method for a rectangular plate. Here the method...
The Earthquake Barrier
The earthquake barrier protects buildings from the horizontal ground vibrations of an earthquake by installing a 'force barrier and an energy barrier' at the...
Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...
A Relationship Between Deformation Modulus and SPT N for Gravels
The results of over 200 horizontal plate load tests performed in situ in large diameter boreholes on gravels at various relative densities are used to develop a relationship between deformation...
