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...
Localization Instabilities Due to Damage and Fracture Propagation: Application to Tensile Specimens
In recent research it has become clear that localization of damage due to strain softening as well as propagation of interactive cracks can result in bifurcations of the loading path characterized...
Compressive Strengths of Lean Concretes Containing Fly Ash
The compressive strength development of lean concretes containing fly ash was evaluated. Concretes were prepared at total cementitious materials contents of 423, 517, and 564 lb/yd3...
Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...
Design and Performance of Earth Retaining Structures
The proceedings of the 1990 Specialty Conference on Design and Performance of Earth Retaining Structures was held in Ithaca, New York from June 18-21, 1990. It presents a total of 50 papers...
The Dredging Dilemma
Disposal of dredge materials is becoming a national environmental problem. Disposal sites on land are becoming extremely scarce and environmental objections growing. There are also objections...
Siphon Quenches Drought
An age-old engineering concept�the siphon�enjoys new success in alleviating a severe water shortage at the Ketchikan Pulp Company's Ward Cove Pulp Mill. With major layoffs...
Commentary on Building Code Requirements for Masonry Structures (ACI 530-88/ ASCE 5-88) and Commentary on Specifications for Masonry Structures (ACI 530.1-88/ ASCE 6-88)
U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...
Serviceability and Durability of Construction Materials
The proceedings of the Materials Engineering Congress held in Denver, Colorado from August 13-15, 1990 include papers from 37 sessions that address the theme Serviceability and Durability...
Building Blocks for the Future
In the near term, advanced, conventional materials�namely higher-strength steel and concrete�will dominate infrastructure rehab. New steels of higher strengths and toughness are increasingly...

Management and Legislative Implications
American Experiments with Laminated and Multiple-Membered Arches
This chapter explores the history of laminated and multiple-membered arches in America....
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Building Moon Bases
It is widely accepted that the U.S. will begin to build a base on the moon at the turn of the century, and much of the design work has already been done. Based on papers presented at Space...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Some General Remarks on the Structural Behavior and Load-Extension Characteristics of Coated Fabrics with Special Reference to PTFE-Coated Glass-Fiber Fabric
The understanding of fabric behavior, and of coated fabrics in particular, is essential for the design and analysis of fabric structures. Although many research papers have been published...
Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...
Effect of Imperfections on Structural Performance
This paper briefly describes the effect of initial crookedness and residual stress on the behavior of steel members. Both imperfections are unavoidable consequences of modern fabrication...
Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...
