Applications of Fuzzy Mathematical Programming in Structural Optimization
In this paper, several applications of fuzzy mathematical programming in structural optimization are reviewed and discussed. In addition, a formulation of optimum earthquake resistant...

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...

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...

A KBES for Seismic Design of Buildings
A knowledge-based expert system for earthquake resistant design of buildings is described. The knowledge-intensive nature of the domain and the consequent motivation for an expert-system...

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...

A Knowledge-Based System for Evaluating the Seismic Resistance of Existing Buildings
The large number of existing buildings designed without considerations of seismic loading warrants the development of computer aids for the evaluation of their seismic resistance. Since...

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...

Methodology in ODSEWS-2D-II for Optimum Design of Structures to Seismic and Wind Forces
This paper presents the theoretical derivations and numerical procedures used in the computer program called ODSEWS-2D-II for the analysis and optimum design of 2-dimensional regular and...

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...

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...

Seismic Resistant Low-Cost Masonry Buildings in Peru
Future housing in developing countries will be provided mainly in medium rise, four to six stories, bearing wall masonry buildings. This paper reports on the rationality behind this political...

Low-Cycle Fatigue Reliability of Offshore Structures Subjected to Earthquakes
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability...

Lessons Learned from Dynamic Tests of Shear Panels
Thirteen 8-ft by 8-ft shear panels and fifteen 16-in by 18-in shear panels were tested dynamically at the Structural Testing Laboratory, Richmond Field Station, University of California,...

Current Research and Future Developments
A review of current research projects at the National Science Foundation on bridge engineering are reviewed and discussed with respect to immediate and future impacts. A look into the...

Energy Approach of Earthquake-Structural Design Analysis
A new procedure developed from the earthquake energy concepts is presented in this paper. A short-squat building and a long-slender building are analyzed using the presented procedure....

Aerodynamic Methods for Mitigating Wind-Induced Building Motions
Excessive wind-induced motions of tall buildings most frequently result from vortex shedding induced across-wind oscillations. This form of excitation is most pronounced for relatively...

Tuned Liquid Damper and Its Application to Tower-Like Structures
A new kind of damper, Tuned Liquid Damper (TLD) relying upon motion of, shallow liquid in a rigid container for absorbing and dissipating the vibrations energy is explained. The performance...
