Efficient Probabilistic Structural Analysis Using an Advanced Mean Value Method
An advanced mean-value (AMV) method for probabilistic structural analysis is presented. This method blends the conventional mean value method with the advanced structural reliability analysis...

Time Variant Reliability Analysis Using Bivariate Diffusive Crack Growth Models
This paper is concerned with the development of a time-dependent reliability concept. The time variant load carrying capacity, i.e., resistance, of a structure caused by fatigue is expressed...

Markov Approximation to Fatigue Crack Propagation
The distribution of the time required by a crack to reach a specified length and the distribution of the crack size itself are determined. To this end, the fatigue crack propagation growth...

Challenges in Stochastic Structural Mechanics
Currently there are the emerging developments in stochastic computational mechanics, which includes stochastic finite elements and its applications in problems of random systems and random...

Nonstationary Random Vibration with REDUCE
Computerized symbolic algebra, in conjunction with the code REDUCE, is utilized in dealing with nonstationary random vibration of single-degree-of-freedom systems. Application of REDUCE...

Outcrossing Rates By Point Crossing Method
The point crossing method is applied to compute outcrossing rates for general safe domains, i.e., nonlinear load combinations problems. For stationary processes the method typically yields...

An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...

Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...

An Intelligent Design Support System for Computer-Aided Site Development
This research proposes an intelligent design support system (DSS) integrated with a CAD environment for building site planning and development. The DSS is used for providing a good initial...

A Rule Based Expert System for Reservoir Operation
Recent advances in artificial intelligence and expert systems development have attracted many scientists and researchers. Reservoir operation is an ideal field for such research due to...

Managing Microcomputer Applications
The authors have recently completed a study of microcomputer usage in Corps of Engineers planning activities. The study developed a training document for Corps managers, entitled 'Managing...

Living with a Macintosh in an IBM World
The Macintosh computer is widely praised for several characteristics: high resolution graphics, common program user interface, user friendliness including extensive use of a mouse, and...

Making Microcomputer Based CADD Systems Productive
The introduction of microcomputer based CADD systems has made CADD affordable to small engineering firms. Many have not been able to make their CADD system productive. The sources of poor...

Using the Microcomputer in the Software Development Process
The migration of the computer from the controlled environment of a computer room to the office desk-top provides the software engineer with a convenient and effective tool for enhancing...

Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...

Hydrologic and Hydraulic Calibration?A Case Study (a)
The Addison Creek watershed is in Cook and DuPage Counties just west of Chicago, Illinois. Because the watershed has a history of major flooding, eight major stormwater and flood control...

Terrain Modelling for Computer-Aided Site Development
This research proposes a terrain model and a storm drainage model to be used as tools in creating a more efficient design/approval stage of the development process. This research proposes...

Computerized Bridge Coding for HEC-2 Applications on I.B.M. P.C.
A computer program for conversion of survey field notes directly into SB, BT, and GR cards with simultaneous cross-section plot is described. It was designed to simplify the coding of...

Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...

Floodplain-Management Plan Enumeration
A branch-and-bound enumeration procedure can improve the search for an optimal floodplain-management plan. The procedure compares the net benefit of all possible combinations of proposed...
