This paper describes the computational aspects and computer usage history of numerical simulations of horizontal, free surface, steady or unsteady two-dimensional flow fields. The focus...
Parametric Analysis of APM Operational Components: Stopping Policy, Stations and Headway
This study examines generically relationships among the three parameters using a single line transit system. Optimization models are developed to determine the optimum number of stops...
Dynamic Simulation of a DPM Auto Intercept System
This paper reports on the application of the UMTA Station Simulation Model (USS), which incorporates a dynamic path-choice algorithm, to model the diversion of motorists to a downtown...
Joint Flexibility in Steel Frames
This paper investigates the effects of connection flexibility and panel zone deformation on the behavior of plane steel frames. The incorporation of these factors in frame analysis will...
Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...
Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...
Can We Save the Ogallala?
The useful life of the Ogallala Aquifer, which underlies seven western states, can be extended indefinitely through water conservation in the widest sense of the term. In addition to optimization...
Danger: Natural System Modeled by Computer
Computer (mathematical) models are written to simulate such natural systems as those leading to acid rain, flooding, or toxic waste migration from disposal sites into groundwater. In some...
Computer Keeps New Orleans: Head Above Water
The city of New Orleans has been beset with drainage problems since its founding in 1718. A major drainage system was installed in the city in the late 1800s, but it has grown increasingly...
Simulating Construction Operations by Microcomputer
Field operations on major construction projects involve complex interactions among construction equipment, materials and supplies, skilled craft resources, and technical and administrative...
Modeling Construction Companies
This paper reports on the development, implementation, and practical use of a micro-computer based system which simulates the organizational performance of construction companies. The...
Continuum Modeling of Periodic Truss Structures
Procedures for deriving equivalent stiffnesses for an extended Timoshenko beam used to represent truss beams are presented. A typical substructure of a truss is used to calculate these...
Continuum Modeling of Discrete Structures with Geometric Nonlinearities
The modeling of geometrically non-linear discrete structures by an equivalent continuum is presented. The discrete-continuum analogy is developed by first isolating a unit cell of the...
Use of Computer Graphics in the Analysis of Large Space Structures
This paper illustrates how interactive computer graphics can provide a useful tool in setting up analytical models of structural latticeworks comprised of large numbers of degrees of freedom...
Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...
Evaluating Nonlinear Soil Behavior Using the Resonant Column
An analysis is presented that attempts to match a mathematical model to the nonlinear behavior obtained from the resonant column test. This model consists of an oscillator with a restoring...
Centrifuge Model Testing with Dynamic and Cyclic Loads
This paper examines the use of small-scale tests on centrifuges to study a wide range of problems in soil dynamics - including machine foundations, structures and explosion effects. The...
Energy Forecasting Techniques: An Overview
This paper provides an overview of the primary forecasting techniques employed by electric and natural gas utilities to predict energy consumption and demand. Although the techniques discussed...
