Modelling of Tubes with Large Plastic Deformation
A thin circular tube laterally compressed between two rigid plates is investigated for its load(P)-displacement(?) behaviour. The moving hinge concept yields a good prediction compared...
Optimum Design of Laminated Metal Matrix Composites
With the increased demand for high-strength, lightweight materials that function successfully in high temperature environments, the effective development of metal matrix composites has...
Pipeline Rehab: Underground Options
While simply digging up old pipes and replacing them is sometimes still best, other alternatives can give long life while easing the strain on the community. Trenchless methods for on-line...
Dynamics of Composite Tubes
A displacement-based stiffness method is used to study the characteristics of dispersive wave propagation in laminated composite cylindrical tubes. It is assumed that the tube is composed...
Inelastic Stability of Thin Walled Metal Tubes Under Cyclic Loading Conditions
This paper is concerned with an experimental investigation on the inelastic stability behavior of thin-walled tubular specimens of steel, aluminum and stainless steel, under cyclic loading...
Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...
Optimal Design of Tall RC Tube Buildings
The analysis and design of reinforced concrete framed tube buildings is formulated as a nonlinear optimization problem and solved using modern design optimization software. The influence...
The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...
The Use of Polyurethane Grouts and Grout Tubes
Most polyurethane grouts used for seepage control are one-component, and water activated. They are prepolymers of a polyisocyanate with a polyol. Some of the polyurethane grouts use an...
Cyclic Behavior of Concrete-Filled Tubes
This paper presents the results of tests on hollow and concrete-filled rectangular tubes subjected to cyclic bending and buckling. It is shown that concrete infill greatly improves the...
Circular Tubes and Shells 4th Edition of SSRC Guide
The 3rd edition of the Guide was the first to have a chapter devoted to Cylindrical Tubes and Shells. Chapter 14 in the 4th edition is a major revision of Chapter 10 in the previous edition....
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
The Quiet Revolution in Skyscraper Design
Since the 1960's, there has been a major change in the philosophy for designing high-rise buildings. Up to that time, most buildings were designed to resist wind forces by...
Exxon's Offshore Platform Nearly Doubles Water-Depth Record
In 1976, Exxon erected near Santa Barbara (Los Angeles metropolitan area) the Hondo platform, in 850 ft of water. This is nearly twice the previous record depth established in the North...
The Modernization of a Small Hydro Plant
The Cornell Hydro in Northern Wisconsin was torn down, rebuilt, re-equipped and put into profitable operation. After extensive structural modifications to the old plant, three new 10,000...
Stability of Structures Under Static and Dynamic Loads
Proceedings of the International Colloqium on Stability of Structures Under Static and Dynamic Loads, held in Washington, D.C., May 17-19, 1977. Sponsored by the National Science Foundation....
Paul Bunyan Among Offshore Steel Structures
The world's two largest drydocks, the larger 1,150 x 800 ft in plan were used to assemble on land the four steel jackets. They now stand in the North Sea in about 400-ft of...
