Superquadric Object Representation for Dynamics of Multi-Body Structures
While the finite element representation of an object in terms of nodal coordinates and shape functions is ideal for representing the stress and energy state, it is not well suited to the...
Discrete Optimization of 3D Steel Frames
The purpose of this paper is to report the results of the application of a general discrete optimization procedure to the design of a realistic, three-dimensional steel building frame....
Vector Optimization of Structural Systems
In this paper the basic ideas of vector optimization are presented, and both the weighting and constraint methods are applied to vector optimization of truss systems by minimizing the...
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...
Optimization for Exact Stability of 2-Bar Trusses
This paper is concerned with the structural optimization problem of minimizing the weight of a 2-bar truss subject to nonlinear stability constraints. Optimization problems for stability...
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...
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Development of Analytical Models for Reinforced Concrete
A computer program called WCOMR was developed to analyze the characteristics of RC walls subjected to reversed cyclic loading. The WCOMR comprises RC element idealization described by...
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...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
N-Pad?A Three-Dimensional Program for the Analysis of Base-Isolated Structures
N-PAD is a three-dimensional computer program especially written for the analysis of base-isolated structures. The program is designed with the ability to model various types of isolation...
Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....
Seismic Evaluation of a Tall Reinforced Concrete Frame Building
Accelerations at basement, fifth and tenth floor levels of a reinforced concrete apartment building were recorded during the October 1st, 1987 Whittier-Narrows earthquake. These accelerations...
The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...
Beams on Elastic Foundations: A New Approach
Using the Vlasov model, Vallabhan and Das have developed an effective iterative technique to solve the beam-on-elastic-foundation problem where the soil is assumed to have a uniform thickness...
Patterns of Erosion Along the Atlantic Coast
Shoreline erosion data are needed in the implementation of recent legislation that authorizes the National Flood Insurance Program (NFIP) to provide advance insurance payments for the...
The Geographical Information System of the Brazilian Coastal Management Program
The paper discusses the coastal management program presents; and two modules which are intimately associated and integrated with the system of geoenvironment information: the Zoning and...
The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
