Object-Oriented Design of Finite Element Programs
This paper describes an implementation of the finite element method based on computational abstractions of both mathematical and engineering concepts. In contrast with conventional approaches,...

Finite Element Computations on a Linear Systolic Array
This paper describes a linear systolic architecture designed specifically for finite element computations. Examples of various sparse matrix and vector operations are given. Applications...

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...

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...

Plates and Shells with Crack-Like Flaws
The formulation of new hierarchial finite elements for the analysis of laminated plates and shells in the presence of flaws are discussed. The performance of the elements is evaluated...

Stress Computations for Nearly Incompressible Materials
Computation of stresses by the finite element method (FEM) in the case of nearly incompressible isotropic elastic materials is discussed. It is shown that for moderately high Poisson's...

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...

Computers in Civil Engineering Education at Clemson University
This paper describes the current use of computers in the civil engineering undergraduate education of students at Clemson Univrsity, the land-grant university of the State of South Carolina....

CADD for the Structural Engineer
There is a need for educating structural engineers on Computer Aided Design and Drafting (CADD) programs. Many structural engineering firms use a combination of in-house and commercially...

Early Integration of Computational Methods in the Engineering Curriculum
Practicing civil engineers are continuing to take greater advantage of computers to solve structural problems of increasing complexity. To prepare for practice, engineering students must...

Some Interactive Graphics and Parallel Processing for Earthquake Engineering
Ongoing research at Cornell University on computer-aided earthquake engineering of building structures is exploiting innovations in computing in several areas. Although some of the approaches...

Parallel Computation for Linear Programming
In this paper, the basic Simplex algorithm is reexamined. Computational steps which can be done in parallel are identified, and a parallel version of the Simplex method is implemented...

Polypropylene FRC In Steel Deck Composite Slabs
Engineers, testing laboratories, universities and metal deck manufacturers have studied polypropylene fiber reinforced concrete (FRC) and compared the results with similar slabs reinforced...

Cracking Behavior Comparisons Between Normal and Fiber-Concretes
A comparative study of the cracking behavior of plain- and polypropylene fiber concrete was performed. Both high- and low-strength concretes were studied. Maximum and average crack widths...

High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...

Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...

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...

Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....

Concrete Lunar Bases
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...

Recent Development of Cement-Based Materials
Development of advanced techniques has enhanced the capability of more accurate characterization of engineering materials at both the microscopic and macroscopic levels. Through better...
