Forty Years of Computational Hydraulics?1960-2000
The definition of computational hydraulics as used herein is: the application of numerical methods for the solution of problems of hydraulic flows, largely as practiced by the civil engineering...
Redundancy Evaluation of Existing Bridges
The redundancy of an existing bridge can only be correctly assessed by considering the full superstructure as a single entity. Any formulation based on the analysis of bridge components...
Safety of Long Span Highway Bridges Based on Dynamic Response
This paper consists of an analytical study regarding the dynamic response of highway bridges subjected to heavy vehicle loads, with emphasis on long span low fundamental frequency bridges....
Design Rainfall for Pennsylvania
The most commonly used source of rainfall estimates is the U. S. Weather Bureau Technical Paper 40. A more detailed study of Pennsylvania storms was conducted in 1970 under the sponsorship...
Design Storm Selection for Stormwater Management Master Plans
The design rainfall event is an important performance standard for a stormwater management master plan. A stormwater master plan for Virginia Beach, Virginia, is used as a case study to...
A Versatile Methodology for Flood Frequency Analysis
Many observed annual flood series exhibit reverse curvatures when plotted on lognormal probability paper. The occurrence of these curvatures may be attributed to storm and basin factors....
Groundwater Modeling - A Management Tool
A hydrogeologic investigation within the South Mountain Complex of south central Pennsylvania was performed to develop a groundwater management program. Using LandSat imagery, low altitude...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...
Development, Use, and Synthesis of S-Graphs
A study to identify S-graphs from the southwestern United States has been completed. This study has resulted in the compliation of 53 S-graphs, documentation of some of the watershed characteristics,...
Reliability of a Frictional System with Uncertainty
In recent years, more emphasis has been placed on the study of random vibration of structures with uncertain parameters. Most of these have dealt with second order statistics of the response...
Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...
A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...
Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...
Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...
Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...
Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...
Dynamic Simulation of Foundations on Winkler Subgrade
The objective of this paper is to present a dynamic simulation of foundations on Winkler subgrade. The analysis is based on a direct simulation procedure. The structures have been modeled...
Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction
A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst...
Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...
