Integration of a Traffic Noise Model and AutoCAD
TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical...
An Expert System for Stop-Controlled Intersection Design
In 1915, the first stop sign was installed in Detroit, Michigan, but until now, there was still no one coordinated body of knowledge which would dictate design and analysis requirements....
Trip Generation Analysis by Artificial Neural Networks
A new approach for conducting trip generation analysis based on the concepts of artificial neural networks is presented in this paper. First, a brief introduction to the concepts of artificial...
The Use of Linked Spreadsheets as a Transportation Problem Solving Tool
Spreadsheet modeling is a useful tool for business as well as engineering applications. Until the advent of linked spreadsheets this type of modeling was based on the concept of preparing...
Block Dynamics Modeling in Support of Seismic Design
The behavior of an underground excavation is usually characterized by stresses and displacements which develop around the excavation as a result of prevailing field conditions. For conventional...
Options for Dynamic Analyses of Underground Facilities
Continuum and discontinuum modeling techniques for conducting dynamic analysis of underground facilities of geologic repository are discussed. Compared with continuum analysis, the discontinuum...
Dynamic Response of Tunnels in Jointed Rocks
We describe the application of the Discrete Element Method (DEM) to the dynamic analysis of the response of tunnels in jointed rocks to earthquake loading. In situations where large motions...
Stress Wave Loading of a Tunnel: A Benchmark Study
Five different finite element or discrete element computer codes were used to solve a sequence of problems leading to the problem of stress-wave loading of a circular tunnel in a jointed...
Design and Performance Requirements for Surface Facilities of a High Level Nuclear Waste Repository
This paper describes three important steps in the design process of repository surface facilities: (1) Establishing performance requirements and risk levels, (2) translating performance...
Seismic Design Criteria for Transporation Structures
Presented is a discussion focusing on two critical issues which must be resolved when setting seismic design criteria for important transportation structures such as those supporting elevated...
Controlling the Seismic Behavior of Precast Concrete
Precast concrete has, through the years the years, acquired a bad reputation insofar as its ability to withstand earthquake is concerned. This reputation, though reasonably based, is not...
Analytical Platform Development for Precast Structural Systems
The multi-investigator PRESS (Precast Seismic Structural Systems) research project requires an analysis tool that can be used to perform nonlinear seismic analyses of a wide variety of...
Ductile Connections for Precast Concrete Frame Systems
This paper describes a research program to investigate the behavior of ductile connections between precast beam-column elements. The objectives of the program are to provide rational design...
