A Fatigue Study of Prestressing Strand
Strand fatigue data reported in the literature and also from recent tests were combined to form a data base of strand fatigue data which was analyzed using regression analysis techniques....
Axial Fatigue Model for Wire Rope Strand
A numerical fatigue model for cables and rope strand subjected to fluctuating axial tension has been developed. This model determines the maximum wire nominal and Hertz contact stresses,...
Large Reinforced Concrete Active Reclaim Silos
The design and construction of large reinforced concrete shell silos used to provide economical short-term protected storage for coal and lignite in the active reclaim systems of power...
Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....
Mechanical Properties of Model Ice Rubble
Experiments were conducted to measure the mechanical properties of bulk ice rubble. Tests were performed under isothermal and plane strain conditions. Fresh water ice blocks were used...
Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
Design and Manufacture of Turbine Runner Blades Using CAD/CAM-Technology
Interactive blade design, fluid flow analysis, stress analysis and NC-matching of both model and prototype blades are working from a common data base and are demonstrated in this paper....
Hoover Dam Plus Fifty Years Equals El Cajon Dam
The completion of El Cajon arch dam on the fiftieth anniversary of the completion of Hoover Dam has given the opportunity to compare design and construction of two concrete arch dams constructed...
Dam Safety Relating to Merwin and Yale Hydroelectric Projects
This paper describes the safety investigations performed to evaluate the dams, associated with the Merwin and Yale Hydroelectric Projects, for the effects of severe floods and earthquakes....
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Microcomputer Program for Bridge Analysis & Rating
The microcomputer software system, BRCOM, for the analysis and rating of bridge superstructures is described. The system consists of ten programs written in UCSD P-System FORTRAN, which...
Interactive Analysis and Design Program for Girder Bridges
An interactive microcomputer program for the analysis, design, and rating of girder bridges is presented. The program, GBRIDGE, is user-friendly, menu-driven, and developed in modular...
Study of Structural Behavior with Computer Simulation
The application of computer simulated testings of structural elements in the civil engineering undergraduate education is described. With a computer simulation a structural component may...
Creep Modelling for Masonry under Plane Strain
A computational procedure based on the principle of superposition to estimate creep strains in composite masonry walls is developed and presented in this paper. This development is based...
Equation Solving on a Parallel Computer
The application of computers to the analysis of large structural systems is examined. The analysis procedure is presented as three distinct phases: (1) element formulation, (2) equation...
Mechanics of Crack Propagation in Stiff Clays
Many stiff clays forming part of natural slopes and earth dams exist in the fissured state. When these cracks are subjected to gravity induced normal and shear stresses they may propagate....
A Laboratory Investigation of the Undrained Small Strain Behavior of London Clay
Three different total stress-paths were followed during shearing of the anisotropic consolidated (CAU) tests: compression, extension and a stress-path simulating an element under a plate...
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Training Programs for Engineering Consulting Firms
Engineering consulting firms heavily use and support in-house training programs. The objectives of these training programs are to: (1) supplement the graduate engineer's educational...
