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...
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...
Virginia Case Studies of Risk Based Drainage Design
The goal of this paper is to apply a practical engineering risk-based method of design of pavement and surface drainage systems to three Virginia case studies. The target systems include...
Comparison of Storm Water Management for Phoenix and Washington, D.C. Urban Areas
The design criteria, the methods of analyses, and the estimated costs of construction are compared for two storm water management systems in the Phoenix, Arizona and the Washington, D.C....
Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...
Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...
Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....
Hydraulic Performance of Berm Breakwaters
In recent years, the concept of unconventional rubble mound breakwaters, i.e berm breakwaters, has gained much attention among researchers and engineers as an economical method to build...
Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
Experimental and Historical Verification of the Performance of Naturlly Armouring Breakwaters
