Progress in Hydromechanics
The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided...
Superstructure: Statics Discussion
This chapter briefly discusses the statics of the Colossus....
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...
Notable Unbuilt Bridges
In the examples of unbuilt bridges discussed, many different ideas and concepts have been proposed. Most appear to be basically sound in nature, although rather innovative and daring....
Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...
Neural Network Approaches in Structural Mechanics Computations
The neural computing paradigm has not been extensively researched in terms of its applicability to a wide variety of structural engineering problems. At an intellectual level this research...
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...
Two-Level Optimization of Nonlinear Structures
This paper presents several optimization design problems and their applications to both cable structures and geometrically nonlinear braced-rib arches. The sum of squares of residuals...
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...
Experience with the p-Version Program PROBE
The conventional approach in the FEM is known as the h-version, in which the solution accuracy depends on the size h of elements. The alternative approach is the p-version, in which the...
Natural Aggregates in Structural Lightweight Concrete
Pumice and scoria have been used in structural concrete since the days of the Roman Empire. Records for the past five decades show minimal use of these materials in structural concrete...
Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...
Sulfate Attack on Concrete Containing Fly Ash
The use of fly ash as a portland cement replacement in concrete may provide many technical and economic advantages. One such technical advantage is to improve the resistance of concrete...
Application of BEM to Two-Dimensional EPFM
This paper describes the authors' current and continuing research in application of the Boundary Element Method (BEM) to crack growth problems in Elastoplastic Fracture Mechanics...
Service Life of Underground Concrete Structures
The service life of underground concrete depends on both the physicochemical properties of the concrete materials and the properties of the in-service environment. The major factors controlling...
Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...
Early Age Strength Detection for In-situ Concrete
In recent years it has become increasingly beneficial to know the quality of concrete as soon as possible after it has been placed. This is especially true for high-rise concrete buildings...
