A Study on Non-Conforming Boundary Elements in Elastomechanics
This work is a critical study on the performance of non-conforming boundary elements in three-dimensional elastomechanics. The pervasive way of implementing the boundary element method...
3-D Flexible Embedded Machine Foundations by BEM and FEM
A study on the dynamic response of three-dimensional flexible massless foundations of arbitrary shape, embedded in a homogeneous, isotropic and linear elastic half-space and subjected...
Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
An Integrated Approach to Structure and Control Design of Space Structures
In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints...
The Effects of P-Delta and Semi-Rigid Connections on Response Behavior of Inelastic Steel Frames Subjected to Cyclic and Seismic Loadings
A numerical method is presented for analyzing semi-rigid connected steel frames subjected to various time-dependent excitations with consideration of damping, nonlinear material behavior...
A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...
Impacts of Risk-Based Analysis on Current Design Practices
A summary of hydrologic design standards used by selected federal agencies for the safety evaluation of dams is presented. A computational procedure is outlined to develop hydrologic design...
The Ultimate High Tide
Unprecedented consumption of fossil fuels and clearing of vegetation have spurred interest in the greenhouse effect. Under this scenario, a build-up of carbon dioxide and other gases in...
Structural Applications of SIFCON
SIFCON (Slurry Infiltrated Fiber CONcrete) is a relatively new composite material utilizing steel fibers in a cement-based matrix. It differs from conventional steel-fiber-reinforced concrete...
Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...
Influence of Surface Conditions on Surface Temperature
Geotechnical engineers working in areas of discontinuous permafrost are frequently faced with the necessity of designing facilities with a minimum of thermal disturbance. Construction...
Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
Hydraulic Transient Analysis on a Micro Computer
The shift toward micros has reduced prices and increased accessibility, permitting engineers to bypass 'bureaucratic' DP departments and run programs as often...
Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...
Quality Assurance in a Large Firm
This paper will describe the formalization of the Quality Assurance Program in a large consulting engineering firm. Although Quality Assurance and Quality Control have been a part of normal...
The Charles River Project
The Charles River Project received the 1984 Presidential Award for Design Excellence in Architecture, Engineering, and Urban Planning. Sited between Charlestown and Boston's...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Design and Effectiveness of Urban Retention Basins
Retention basins are recommended by practicing engineers and regulatory agencies for stormwater management in new land developments. They may require considerable space which limits their...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
