Study of the Collapse of a Reinforced Concrete Model Structure Under Simulated Earthquake Motion
The collapse, under simulated earthquake motion, of a multistory r/c frame structure with columns flexurally weaker than beams (SBWC) is studied. A small-scale model, comprising parallel...
Microcomputer Application of the Florida Standard Urban Transportation Modeling Structure
Over the past five years the Florida Department of Transportation (FDOT), in conjunction with the twenty-one Florida Metropolitan Planning Organizations, has developed the Florida Standard...
Methods for Real-Time Control of Highway Traffic
The paper describes the development of computational strategies for demand-responsive decentralized traffic signal control. First, a Dynamic Programming procedure is developed which serves...
Fuzzy Sets Bring Ideas Into Focus
Fuzzy set theory was born out of a dissatisfaction with classical crisp sets and binary logic. Conventional computers, despite 30 years of evolution, are still rigidly precise, number...
Pipeline Frost Heave Predictions Using a 2-D Thermal Model
Chilled structures founded on initially unfrozen soils cause a zone or 'bulb' of frost to develop with time. This time period may be of seasonal duration, as...
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...
Some Recent Advances in Automatic Mesh Generation
The establishment of automated finite element modeling procedures must begin with the development of automatic mesh generators capable of producing a valid finite element mesh for any...
Modern Methods for Automatic FE Mesh Generation
An overview of the various Finite Element mesh generation techniques is presented. Since most automatic FE Mesh Generation techniques read in geometry of the object and create meshes on...
Automating Three-Dimensional Finite Element Mesh Generation
A number of important advances and contributions to the topic of computer aided finite element mesh generation have been made by the Mathematics Department at the General Motors Research...
Hydrologic Modeling Using Radar-Rainfall Imagery
A flash flood forecasting system is being developed which has three main elements: 1) high resolution estimation of rainfall in time and space using radar and ground-based gages; 2) computer...
A Microcomputer Reservoir Decision Model
The paper discusses the development of a dynamic programming model to optimize reservoir operations. Given statistical summaries of inflows, forecasts of near-term inflows, and cost statements...
Water System Data Base for Naples, Florida
Boyle Engineering Corporation has developed a comprehensive database technique using its Intergraph Computer-Aided Design and Drafting (CADD) system to assist in the computer modeling...
Hydrologic Simulation for Reservoir Development
Potential changes in the Manasquan River basin hydrologic budget were assessed with the Hydrological Simulation Program in Fortran (HSPF). The HSPF results were used to assess the reliability...
PC-RUNOFF and dBASE III for Stormwater Data Management, Planning and Design
A version of the RUNOFF Block of the Stormwater Management Model (SWMM) has been extensively revised for the Microcomputer Stormwater Simulation Manager (MSSM). In addition, PRERUN, a...
Interactive Modeling and Display of Spatial and Time Varying Phenomena Using CAPLIB7
This paper describes some of the software being used at Cornell University to aid the development of tools for modeling phenomena having both spatial and temporal dimensions. Such models...
Intrinsic Models for Interactive Structural Design
This paper introduces a 'generic' model for interactive design of constructed facilities. The proposed methodology takes real world conditions, in terms of load...
Modeling Construction Operations in the Classroom
Students in construction management need to be exposed to the dynamics of the construction site and become familiar with the interaction of resources. In addition, the student needs to...
